commutator motor

Radio noise may originate at any point where the circuit is interrupted, such as control relays, push buttons, commutator motors and generators, etc.

Most commutator motors are limited to about 1,500 volts because higher voltages give rise to a risk of arcing across the commutator.

Product Range Thyristor Drives for DC commutator motors fed from AC supply.

Today, the motors that propel electric vehicles on land, through water and in the air are mainly brushless because brushed commutator motors are on the way out.

Also around 1889, Elihu Thomson of the American General Electric company developed a recording watt meter (watt-hour meter) based on an ironless commutator motor.

With the GE commutator motor controller operating by air pressure, it had to be redesigned with the advent of the All-Electric PCC.

He initially designed a 2000:1 Borg Warner gearbox, ( which is still in service) driven by a 1 HP variable speed Schrage commutator motor, coupled through, something new for the time, a torque converter.
