Stator Wiring
The locked rotor stator current is equal to the amplifiers continuous rating and for either
low speed or locked rotor conditions the stator must withstand this continuous rating.
Derating the stator wiring for three phase operation should not be done.
Model Locked Rotor
MPA-05-460 5 amps
MPA-09-460 9 amps
MPA-15-460 15 amps
MPA-25-460 25 amps
MPA-35-460 35 amps
MPA-50-460 50 amps
MPA-75-460 75 amps
MPA-100-460 100 amps
For operation at 460 Vac it is recommended that the stator wiring insulation withstand 600
volts.

AC INPUT
A GND connection is supplied as a means to ground the motor frame to earth ground.
If shielded cable is not used, it is recommended that the RST and GND wires be twisted.
NOTE
If the resolver feedback wiring is to be run
adjacent to the RST motor wiring, then the
motor wiring should be 100% shielded (foil
and braid).
