4.24 Motor Components
4.24.1 Function
The motor type employed is a permanent magnet, synchronous speed motor. The winding section of
the motor is similar in design to a standard 3-phase star-connected Stator.
4.24.1.1 Stator
The Stator operates as the force that drives the shaft, utilizing the HV DC pulses provided to the motor
windings by the Inverter.
4.24.1.2 Rotor
The rotor is an integral part of the motor shaft and is a permanent magnet design that allows the
synchronous characteristic required for broad range speed control.
4.24.2 Motor Protection
Conventional motor protection based on incoming 3-phase currents and voltage conditions are
inadequate to protect the motor and electronics in the event of mishap due to the total separation
of the motor windings from the incoming 3-phase current by the DC conversion. Therefore, the bulk
of protection is based on measurements taken by the Inverter and calculations derived from those
measurements.
Motor currents and voltages displayed in the SMT cannot be directly compared or correlated to
incoming 3-phase AC values.
All Stators employ overheat cutout protection utilizing thermistors in each winding. In all models,
except the TTS300/TGS230, Stator temperature initiation and control of the motor winding/shaft
cavity cooling solenoid is provided.
