This manual, Three-Phase Motor Drives, introduces the student to the operation of three-phase, variable-frequency induction-motor drives. Modern implementation of these drive systems allows better motor control which translates into improved power efficiency and significantly reduced power consumption.

3. Conductors with compact and compressed stranding have about 9 percent and 3 percent, respectively, smaller bare conductor diameters than those shown. See Table 5A for actual compact cable dimensions. 4. The IACS conductivities used: bare copper = 100%, aluminum = 61%. 5. Class B stranding is listed as well as solid for some sizes.

The three phase motor is widely used in industry because of it's low maintenance characteristics. Due to the nature of three phase power, creating a rotating magnetic field in the stator of this motor is simple and straight forward. The strength of the magnetic field changes, as the current flow in the coils of wire around the stator poles change.

The three-phase AC motor with motec is a new integrated solution. Our three-phase AC motors are particularly suitable for inverter operation. Modern inverters switch power stages at switching frequencies between 4 and 16 kHz, which can give rise to high rates of voltage rise and overvoltages in the motor windings.

Full load amps for single and 3-phase 460 volts, 230 volts and 115 volts electric motors.

The chart below can be used to select the conductors according to the length of the supply cables and the starting current, in order to limit the voltage drop 

The winding with seriously aged insulation should be exchanged. 4. The induction motor sound is abnormal. In two-phase operation, there is a buzz sound. Restart the motor after shutting down. If the motor doesn’t rotate in two-phase operation, find the reason for phase loss and eliminate it. The three-phase current is unbalanced.
