Characteristic
For general purpose applications, torque
Constant torque remains constant regardless of speed
changes.
For applications where torque changes with
Reduced or
the speed like fans, pumps, and others that
variable torque
require reduced torque relative to the load.
• High starting should be selected only when:
• Wiring between the drive and motor exceeds
150 m
High starting
• Large amount of starting torque is required
torque
• AC reactor is installed
• motor exceeds the largest motor
recommended for that drive used
When operating at speeds greater than 60 Hz
Constant output motor requires constant voltage. Above 60
Hz, motor operates in constant power range.
