14 INDUSTRIAL MOTORS What is VFD? Background Motors which are fed through VVVF drive supply are subjected to rapidly increasing voltage i.e.(high dv/dt). Due to coupling effect of the length of the supply cables coming from the drive, the peak voltage at the motor terminals can as high as 1 V in case of V rates motors. i.e. (x1.1x=1v) The rise of voltage is rapid and depends upon the switching frequencies of IGBT's. These are in the range of 0Hz to khz. Due to the fast rise times of st voltage, the voltage drop across 1. coil from terminals is very high and it can be almost the total phase voltage. Standard insulation scheme with Special impregnation process is suitable for VVVF drive application up to supply voltage of 0V. In some application with VVVF drive where the supply voltage is greater than 0V, the winding has to be designed to withstand additional protection in insulation. This insulation system is called as Special Insulation Scheme. However this execution is limited for voltage up to V only,the peak voltage at the motor terminals can as high as 0 V in case of V rates motors. i.e. (x1.1x=0v) What is a VFD? A VFD is a variable frequency drive. It receives electrical energy from three phase or single phase ac supply. It converts the ac supply to a DC. Then through various switching techniques it inverts DC supply to a three phase variable frequency and variable voltage supply. Load Characteristics Ø When using a VFD-motor in an application it is necessary to know horsepower torque and speed characteristics of the load. Ø Typically there are three types of loads Ø constant torque: conveyor, cranes, positive displacement pump/fan/compressor are the example of constant torque application Ø Variable torque: centrifugal pump, fan, blower, compressor are the example of variable torque application Ø Constant HP: winders, unwinders, drilling machine & certain mixers are the example of variable torque application *Advantages of application of VFD Motors Ø Speed & control: Stator winding of an induction motor develops a rotating magnetic field. The rotating field rotates at constant speed called synchronous speed given by 1x frequency / no.of poles This field induces currents in the rotor which produce torque and rotor speeds up close to synchronous speed. This field induces currents in the rotor which produce torque and rotor speeds up close to synchronous speed. As VFD changes frequency it changes synchronous speed, hence speed of the rotor Ø Heavy load inertia starting (High GD ) : Motor does not get heated up during starting. So there is no limit on number of starts and stops and also connected GD 1

15 INDUSTRIAL MOTORS What is VFD? Load Characteristics Ø High starting torque & low starting current requirement: The current setting of VFD is to be adjusted as per starting torque desired. For example if starting torque of 1% is desired the current setting is t o b e adjusted t0 1%. Ø High efficiency at low speeds. Ø High pf even at low speeds. Ø Vfd motor replaces with advantage DC motors, and slip ring motors. *Major Issues with VFD. Ø It produces voltage spikes that may cause premature failure of windings. Ø It produces harmonics that may spoil power quality. Ø It produces a shaft current that erodes shafts and bearings. Ø Motor heating at lower speeds of operation. *How to overcome major issues with VFD? Ø To with stand voltage stresses insulation levels are improved by using dual coated enamel wires, by increasing thickness of insulation, by sealing electrical joints in the winding, by providing protective coating on overhang portion of winding. Ø Harmonic effects are reduced by using suitable filters externally or inbuilt. Ø Shaft currents are prevented by using insulated bearings in case of higher kw motors. Ø If motor is run continuously at lower speeds and at rated torques either bigger frame is selected or independent cooling motor is provided. Can Standard Motors be used on VFD? Yes, provided speed is not less than rated speed or torque varies as square of speed as in case of fan loads. However, over all life of motor may get reduced to half. Can Hazardous Area Motors be used on VFD? Yes, combined temperature rise test required on motor and VFD being used to determine temperature class of motor accordingly statutory approval to be obtained from customer to specify operation range & type of application. Please refer LHP for such requirements.

36 HAZARDOUS AREA MOTORS Hazardous Area Motors - General Technical Information Hazardous Areas Hazardous areas are defined as areas where explosive atmosphere is present, or may be expected to be present, in quantities such as to require special precautions for the construction, installation and use of equipment. The decision as to whether an area is hazardous as per the relevant regulations and specifications rests entirely with the user, or in case of doubt, with the competent inspecting authority. IS 7:9 classifies the hazardous areas into three zones, depending on the frequency and duration for which dangerous concentrations are likely to be present. Classification of Hazardous Areas (Gases and Vapours) and selection of Electrical Equipment. Classification of these zones and selection of electrical equipment is as under. Table No. 1 Zone Zone '0' Zone '1' Zone '' Classification of area as per ref. std.is 7:9 An area in which Hazardous atmosphere is continuously present Hazardous atmosphere is likely to be present under normal operating conditions. In this area hazardous atmosphere is likely to be present only under abnormal operating conditions and for a short period. Selection of electrical equipment based on ref. std. IS :9 Generally, use of electrical equipment is to be avoided. But when this is not practicable, intrinsically safe or pressurized electrical equipment to be used. For this area, electrical equipment used, must be in flame proof enclosure type Ex(d) conforming to IS/IEC Apparatus with type of protection Ex (e) in accordance with IS/IEC 79-7 may be used without any special enclosure. Apparatus having type of protection Ex (na) in accordance with IS/IEC 79- are also permitted for use.

67 BRAKE MOTORS Brake Motors Table No. - For optimum performance we suggest to use following Rectifiers (Power supply) Brake Coil Voltage AC Input Voltage Rating Rectifier Type VDC 1 VAC VAC 1. Amp 1. Amp EH 7 D EH 7 AD 9VDC VAC 1 VAC 1. Amp 1. Amp EH 7 CD EH 7 BD All RECTIFIERS offered by us are with inbuilt DC switching protection circuit. Use of inferior quality & cheap Rectifiers may damage your costly brake coils. Switching Brake coils are operated with DC voltage. Generally when braking time is not critical AC side switching is done. This method is often used with brake motors. Where brake is switched with motor contacts. Due to the inductance of the brake coil, engagement time can be - times longer than with DC switching. Therefore this arrangement is not suitable for hoist applications. For falling loads such as hoist, lift and cranes, also the high inertia loads, a brake motor to some extent regenerate the supply and hold off the brake. Here it is essential to switch on the DC side of the rectifier. DC side switching requires provision of universal spark suppressor and capacitor to protect the coil and switches against inductive voltages. For normal rectifier converting AC to DC you can use separate universal spark suppressor and capacitor across the switch. Rectifier supplied by us are designed to include suppressor and capacitor suitable for DC switching.

The table shows the delay during engagement t, the rise time of brake torque t1 and the engagement time t1=t+t1 Disengagement time is not influenced by DC or AC side switching. However it can be reduced by suitable excitation or over excitation. For electrical performance please refer Page No.1 to 17. 7
