4 TECHNOLOGY OVERVIEW One of the most common methods of moving a load from point A to point B is through linear translation of a motor by a mechanical leadscrew and nut. This section is here to assist and refresh your understanding of the basic principles of leadscrew technology prior to selecting the system that is best for your application. Please also refer to the Glossary at the end of the catalogue. Some basic design considerations are as follows: 1. What is the load of your system? 2. What is the required speed to move from point A to point B? 3. What is the distance to travel? 4. What is the required time to move from point A to point B? 5. What accuracy does your application require? 6. What repeatability does your application require? 7. Horizontal vs vertical orientation? LINEAR MOTION SYSTEM TYPE A. External Linear 1 B. Non-Captive C. Captive D. Kaptive WHY CHOOSE ONE FORM FACTOR OVER THE OTHER? 1. What is the best mechanical fit for your application? 2. How do you plan to attach the screw? 3. Is rotation of the screw acceptable? 4. Does your application require an encoder or brake? 5. What is the stroke of your application? WHAT ENVIRONMENTAL CONSIDERATIONS DO YOU HAVE? Our linear motion systems are designed to operate in dry and non-corrosive environments. The standard product does not have an IP rating. Operating the linear systems in dirty or corrosive environments will significantly reduce product life. PRODUCT SELECTION There are many inter-related variables to consider when selecting the right linear motion system for your application. Your load and speed requirements will determine other variables such as the size of motor, the lead of the screw and ultimately the voltage and current requirements of your electronic motor drive. Depending on your application, trade-offs can be made 1 External type linear stepper actuator with ballscrew is also available.

5 with many variables as your finalise the system that will meet your performance, form factor and cost specifications. Quantify these basic variables first: 1. Load that you need to move (or push thrust) 2. Velocity 3. Distance to travel (stroke) 4. Time required to move from point A to point B (acceleration required) 5. Torque requirements of your entire system 6. How much backlash is acceptable in your system? 7. What is the required positional repeatability? 8. Is this a vertical or horizontal orientation? To reduce complexity and cost of a design, it is important to accurately size a motor/lead screw combination. Below are a few simple steps in selecting the necessary components for a given application. Step 1 Choose a motor NEMA size (Force requirements) MOTOR SELECTION In order to select the right motor combination with the leadscrew, several factors should be considered: 1. How much force is required? 2. What is the desired step angle? 3. Detent or holding torque requirements? 4. Physical size restrictions? 5. What type of drive (amplifier) are you using? Here is a general overview of the output thrust vs. NEMA size: Frame Sizes Max Thrust Recommended Load Limit NEMA In mm N lbs N lbs NEMA 8 20mm 70N lbs 45N lbs NEMA 11 28mm 150N lbs 140N lbs NEMA 14 35mm 300N lbs 230N lbs NEMA 17 42mm 600N lbs 320N lbs NEMA 23 57mm 1300N lbs 910N lbs NEMA 3 86mm 2400N lbs 2270N lbs As the NEMA size of the motor is increased, the output thrust of the actuator is consequently increased. Step 2 Choose a screw lead (Force and speed requirements) After estimating the required thrust and choosing a NEMA size that may fit your application, the speed and acceleration of the load must be considered and evaluated to choose an appropriate screw lead. Due to the nature of lead screws, the output speed and output thrust achievable by a motor/lead screw combination are two inversely proportional variables (i.e., increasing the required thrust will lower the achievable speed of a motor /lead screw combination). Therefore, the maximum output force of a system is lowered for applications that require higher speeds. For complete motor/lead screw selection data, please refer to the speed/thrust curves for each NEMA size. Motion Control Products Ltd. P a g e 2

6 Although these two steps provide a solid foundation in motor/lead screw selection, other variables must also be considered: Duty cycle Desired life of a System Environmental considerations Positional repeatability Acceptable backlash Acceleration/deceleration requirements Driver specifications Vertical or horizontal orientation Because of the numerous variables involved in motor selection, it is highly recommended for users to proceed with physical testing to accurately determine the motor/lead screw combination required for a given application. NOTE: Although this section aims to provide a rough guide to selectin g a motor/lead screw combination that best fits an application, we recommend contacting our application engineering staff for further assistance with the motor selection process. BASIC SPECIFICATIONS FOR LINEAR SYSTEMS Unless otherwise noted, all reference to leadscrews in this catalogue has the following characteristics: Leadscrew material: 303 Stainless precision cold rolled steel Screw Coating: Teflon coating is optional Standard screw accuracy: inch per foot (0.18mm per 300mm) (Lead accuracy) Screw straightness: in /foot, measured as Total Indicated Runout (TIR). All screws are carefully checked for straightness before shipment. Screw Efficiency: From 35% to 85% dependent on lead. It also depends on the usage of an anti-backlash nut with screw. The larger the lead, the higher the efficiency of the screw. Operating temperature: -20 C to +50 C (-4 F to +122 F) Screw backlash: 0.01mm~0.1mm, depends on different lead. Anti-backlash nut should be considered for high bi- directional positioning repeatability. System backlash: Includes screw, motor, and attached mechanics. This will be the sum of all the backlash in your motion axis. Nut Material: Polyacetal with a lubricating additive. Standard is a free-wheeling nut. [Anti-backlash version is available] Wear life of screw and nut: Depends on load, speed, duty cycle and environmental factors [typically > 5 million cycles] Note: Motion Control Products linear systems are manufactured from high quality materials. Due to the variable effects of friction, lubrication and cleanliness, an exact life cannot be predicted for a given application. Motion Control Products Ltd. P a g e 3 Tel.: (+44)

39 WARRANTY 24 month warranty FIRST YEAR SECOND YEAR Full Replacement Parts Replacement Motion Control Products Ltd. warrants its products delivered hereunder to conform to stated specifications and to be free from defects in materials and workmanship. This warranty shall not apply to any product which shall have been improperly installed or subjected to misuse, neglect or which has been repaired or altered expect by Motion Control Products Ltd. s accredited representative, nor to any product which has been subjected to accident. GLOSSARY ACCURACY OF SCREW It is specified as a measurement over a given length of the screw. For example: in per inch. Lead accuracy is the difference between the actual distance travelled versus the theoretical distance travelled based on the lead. For example: A screw with a 0.5 inch lead and inch per foot lead accuracy rotated 24 times theoretically moves the nut 12 inches. However, with a lead accuracy of inch per foot, actual travel could be from to inches. AXIAL LOAD A load that exerted at the central line of the leadscrew BACK DRIVING Backdriving is the result of the load pushing axially on the screw or nut to create rotary motion. Generally, a nut with efficiency greater than 50% will have a tendency to backdrive. Selecting a leadscrew with efficiency below 35% may prevent backdriving. The smaller the lead, the less chance for backdriving or freewheeling. Vertical applications are more prone to backdriving due to gravity. BACKLASH Backlash is the relative axial movement between a screw and nut at standstill. It is normal for backlash to increase with wear over time. Backlash compensation or correction can be accomplished through the application of an anti-backlash nut. Backlash is usually only a concern with bi-directional positioning.

40 CHOPPER DRIVE A constant current drive is usually bipolar. The chopper drive gets its name from the technique of rapidly switching the power on and off to control motor current. A chopper drive allows a step motor to maintain greater torque of force at higher speeds. COLUMN STRENGTH When a screw is loaded in compression, its limit of elastic stability can be exceeded and the screw will fail through bending or buckling. CRITICAL SPEED Critical speed is the rotational speed of the screw at which the first harmonic of resonance is reached due to deflection of the screw. A system will vibrate and become unstable at these speeds. Several variables affect the speed at which a system will reach critical speed: 1. The lead of the screw 2. The rotational speed 3. End fixity 4. The thrust load 5. Diameter of the screw 6. Tension or compression loading For example the following chart shows that for a screw with a diameter of 3/4 inch and 70 inch length, the threshold for critical speed is 700 RPM.

41 DISTANCE It is typically quantified as either inches or mm, which is the required move distance. DRAG TORQUE The amount of torque to overcome the friction of a system. DYNAMIC LOAD The maximum recommended thrust load which should be applied to the screw while in motion. END MACHINING OF THE SCREW Standard metric or English options are available. Customised end machining specifications may be available upon the request. Please refer to page 31 for details or contact us at (+44) for further discussion. FIXITY The performance (speed and efficiency) of the screw system is affected by how the screw ends are attached and supported. Type of End Fixity Relative Rigidity Critical Speed Factor Critical Load Factor Less Rigid Rigid More Rigid Most Rigid HORIZONTAL OR VERTICAL APPLICATION Vertical orientation applications add the potential problem of backdriving when power to the motor is off and without an installed brake. Vertical applications also have an additional gravity factor that must be part of the load/force calculation. LEAD Lead is the axial distance the nut advances on one revolution of the screw. Throughout this catalogue, lead will be the term used for specifying a screw as it is the linear distance travelled for one revolution of the screw. The larger the lead, the more linear distance travelled per one revolution of the screw. LEFT HAND THREAD Counter clockwise rotation Motion Control Products Ltd. P a g e 38

42 LOAD It is typically quantified as either lbs or kg to move or pounds force (lbf) or kilogram force (kgf) for thrust. LUBRICATION The nut material contains a self-lubricating material that eliminates the need for adding a lubricant to the system. The Teflon coated screw option also lowers friction and extends life of the system. MAXIMUM DYNAMIC LOAD Each NEMA frame size motor has a maximum mechanical load that should not be exceeded. For more information, please refer to Speed / Torque curves for the individual frame sizes. PITCH Pitch is the axial distance between threads. Pitch is equal to lead in a single start screw. There may be more than one thread strand on a single screw. These are called starts. Multiple start leadscrews are usually more stable and efficient at power transmission. RADIAL LOAD A load perpendicular to the screw This is not recommended unless additional mechanical support such as a linear guide is used. REPEATIBILITY Most motion applications put the most significance on the repeatability (vs accuracy of screw) of a system to reach the same commanded position over and over again. For example: A repeatability of ±.005 inch means that after repeated commands to reach the same target position, the linear error will be no more than ±.005 inch. RESOLUTION Incremental linear distance the actuator s (motor) output shaft will move per input pulse RESONANCE Vibration occurring when a system is a mechanical system is in an unstable range RIGHT HAND THREAD Clockwise rotation STATIC LOAD The maximum thrust load, including shock load, which should be applied to a non-moving screw. TEMPERATURE Very high or low temperatures may cause significant changes in the nut fit or drag force. Motion Control Products Ltd. P a g e 39 Tel.: (+44)

43 TENSION OR COMPRESSION LOADING A load that tends to stretch the screw is called a tension load. A load that tends to squeeze or compress the screw is called a compression load. Depending on the size of the load, designing the screw in tension utilizes the axial strength of the screw versus column loading. TIME (t) It is typically quantified in seconds. Time period required for a given distance defines the velocity, acceleration (A), and deceleration needed to reach commanded position. TORQUE The required motor torque to drive just the leadscrew assembly is the total of: 1. Inertial Torque 2. Drag Torque (the friction of the nut and screw in motion) 3. Torque to move load TOTAL INDICATED RUNOUT The amount of wobble around the centre-line of the screw TRAPEZOIDAL MOVE VS. TRANGULAR MOVE There are generally two widely used movement profiles. Depending on the required travel time and distance, different movement profiles can be used. The area under the curves below is the minimum stroke of the linear actuator, its required travel. Trapezoidal Move Triangular Move VELOCITY (V) It is typically quantified as either inches/second or (mm/sec) required for your application. Copyright 2017 Motion Control Products Ltd.
