Electrically powered equipment has entered dairy farming in a big way. Cow milking pumps are used for milking even for a small dairy of 3-4 animals. CG motors are successfully running these machines. Basically it is a vacuum pump motor with sheet metal rolled body for compact size & weight.
Motors in the range of 370 W to 1500 W 2-pole & 4-pole are normally available in drip proof (or open) fan cooled type construction for better cooling of the motor. Specially designed to operate at lower voltages (considering suburban areas) without compromising on efficiency of the motor.
