Synchronous 46 pole highmegawatt motors are commonly used for large compressors in air separation and various gas compression applications Highest installed power reference is 59 MW SM motors are a proven reliable compressor drive technology High efficiency is key to total cost optimization Very high voltage is a new technology opportunity
These contactors are built in several versions — the nameplate on a specific contactor states the authorized ratings. These applications include full voltage control of threephase squirrel cage motors, primary control of low voltage wound rotor motors and circuit switching for low voltage capacitors for power factor improvement.
The woundrotor motors use resistor to connect the rotor windings. The resistance can be adjusted to control the speed/torque characteristis of the motor. To use a variable frequency drive with a woundrotor motor the resistors would need to be shorted. It is also recommended to use a dv/dt filter on the output of the drive to smooth the PWM.

A wet rotor motor is typically an asynchronous squirrelcage motor (see Asynchronous motor) whose rotors and bearings are operated in the fluid handled. These motors require special attention during the design, assembly and commissioning stages to ensure that they are reliably filled and vented and that solids in the fluid handled do not reach the fluidlubricated plain bearings.
