3 Single Phase Motors Working Principle By the nature of the market for FHP Motors, the main demand is for single phase types. The most common of these are Split Phase, Capacitor Start Induction Run, Capacitor Start and Run, Capacitor Start Capacitor Run, and Shaded Pole. In order to be self-starting, an electric motor must have a rotating field. The phase displacement in a 3- phase supply produces this, but a single phase motor requires an auxiliary (starting) winding designed to give a displacement similar to a 2-phase supply before the effect is produced. It can be achieved in various ways, each of which has produced a motor with particular characteristics as follows. Split Phase Start, Induction Run (SP) The starting winding uses fine wire and thus has a higher resistance. It is also arranged to have a low reactance. The current in the start winding thus leads that in the main winding and a rotating field is set up. The start winding works at a high current density and it must be switched out as soon as possible when the machine reaches about 75% speed. These motors are suitable for low inertia loads and infrequent starting. Starting current is relatively large and account should be taken of this, when installing, to avoid excessive voltage drop. Capacitor Start and Run (PSC) Capacitor run motors use a capacitor, permanently connected in series with one of the stator windings, to achieve a compromise between good starting torque and good running characteristics. This design is lower in cost than other capacitor motors that incorporate capacitor switching systems. It achieves better running characteristics than a split phase motor.

4 Capacitor Start, Induction Run (CSIR) A capacitor is inserted in series with the start winding to reduce the inductive reactance to a low or even negative value. The start winding current therefore leads the main windings current by almost 90. A large a.c. electrolytic capacitor is used and, since this is short time rated, it must be switched out as soon as the motor has run up to about 75% speed. These motors are suitable for loads of higher inertia or more frequent starting than with the Split Phase Motors. Starting torque is improved and starting current reduced. Capacitor Start, Capacitor Run (CSCR) A large electrolytic capacitor is used for starting but this is switched out when the machine runs up to speed and a smaller paper capacitor is left in circuit while the machine continues to operate. Thus the good starting performance of the capacitor start motor is combined with the good running performance of the capacitor start and run motor. OPEN-CIRCUITING DEVICES Split phase and all capacitor-start models must have some means of switching the starting circuit out once the motor has accelerated up. A centrifugal switch, a speed sensitive device, opens by the centrifugal action of weighted flyers, generally at 75-80% full load speed. Alternatively, a current relay is adopted. The operating coil is connected in series with the run winding and actuated as the current falls during the acceleration period, thus switching out the starting circuit. The centrifugal switch can also be used solely as a speed sensitive device for operation of external circuits. CAPACITORS There are electrolytic short-time rated capacitors used on capacitor - start models, usually mounted on the motor frame. Electrolytic capacitors might deteriorate when stored without use for long periods. They are normally reactivated by switching the motor on and off.normally rated for 1.7 % Duty Cycle and Temperature of 70 Deg C. Motor Run Capacitors are made up of Metalized Poly Propylene (MPP) and are continuously rated and temperature 85 Deg C.

5 EXTERNAL THERMAL OVERLOAD PROTECTOR (TOP) This overload device is usually mounted in the motor endshield. It comprises a temperature sensitive, bimetal disc with a heater and snap - action switch contacts. It is connected in series with one of the main supply leads. The trigger temperature of the bimetal disc is thus, a function of both the motor mains current, via the heater, and the interior temperature of the motor. The snap action of the bimetal disc is caused by reversal of the disc curvature. The bimetal characteristics offer both automatic and manual reset. If manual reset is required, the normal resetting temperature of the bimetal disc is arranged below that of the normal conditions. It will, therefore, only restart on manual resetting of the bimetal disc. The TOP operates in the following critical overheating conditions: Overload : Here the combination of the abnormally high supply current and rising winding temperature actuates the bimetal disc. Locked Rotor : The abnormally high locked rotor supply current, through the TOP heaters, actuates the bimetal disc much faster than if it were responding only to increasing winding temperature. The characteristics of the bimetal disc are selected according to the particular requirements of each motor. For example, to safeguard against the high starting current of a split phase motor the typical TOP would be designed to operate within five seconds from cold. For the more favourable starting current characteristics of the capacitor-start motor, this period is increased to about twelve seconds. Starting current characteristics of capacitor-start-and-run motors are even more favorable, and because the capacitor is continuously rated and much less vulnerable, operating time for the TOP can be increased up to several minutes. Fitment of TOP is designed to limit 1. Initial peak temperatures under stalled motor conditions 2. Under prolonged stalled conditions after the first hour will not exceed 3. Under overload conditions the following temperatures should not be exceeded : EMBEDDED THERMAL OVERLOAD PROTECTORS Small thermostat device, set to operate at C and connected in series with the mains supply, are usually considered adequate protection on general purpose motors. These are inexpensive and auto-reset type. ( Embedded inside the windings) RELIABILITY Each component goes through rigorous quality control at every stage of manufacture. With well-equipped material testing laboratories to back up the modern manufacturing process, the final product is a highly reliable motor. Use of critical components ( Capacitors, Winding Wires, Centrifugal Gears, OC Switches, Thermal Protectors etc) from the world s leading suppliers also enhances the reliability of our products.
