Motors can be powered by many sources including gasoline, diesel, and most commonly electricity. They distribute power through a drive shaft and in many cases via a gearbox. The drive shaft usually spins at high speed before any required gearing takes place. Motors are used in almost every industry and type of environment, serving a wide range of purposes.

Electro-Sensors' Speed Switches are used on Motors to monitor critical speed and guard against slowdown or stoppage that can result in costly process downtime, machine damage, and material waste. Ratemeters and Tachometers are commonly used in this type of application to display the RPM of the motor. Rotary Shaft Encoders can be used to convert shaft rotation into output pulses. Digital Ring Kits provide digital feedback from motors with NEMA C face end bells.
