- Permanent magnet A.C. Motor.
- Instant start, stop and reverse characteristics.
- Basic constant Synchronous speed at 50 Hz is
60 RPM.
- Higher torque and reduced speed through gear
assemblies.
- Built in overload protection - Motor stops,
if overloaded, without burnout.
- Popular choice for precise positioning application.
- Starting, operating and stalling currents are
identical.

- Voltamp motors are usually operated from single
phase source with R.C. phase shifting network. They are essentially
two phase motors and do not require phase-shifting network
when used with two-phase power supply.
- The speed of the motor is directly proportional
to the applied frequency.
- The motor reaches its full synchronous speed
typically within 5 to 25 milliseconds.
- The output torque of the motor is linearly
proportional to the applied input voltage. For intermittent
operation, this characteristic can be used to provide increased
torque.
- The use of reduction gears with the motor provides
increased torque and decreased speed. Output speed is decreased
and torque increased by the factor of the gear ratio used.
Gear losses are typically around 10% per mesh.
- Step-down gearing offers even greater gain
in inertial load rating since the inertia moving capability
increases by the square of the gear ratio.
