28MM*28MM Nema 11 Compact In Volume Dc Brush Gear Motor 24 V
A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy.
They are applied to:
1. In Automobile industry: various fan, wiper, spray pump, turbo timer, rearview mirror etc;
2. In Hotel: automatic door, automatic door locks, automatic curtain, automatic water supply system etc;
3. In Industry and agriculture: PMDC motors are widely used in electrical and automation control and instrumentation;
4. In Medical and healthcare industry: PMDC motors are used more widely, such as medical instruments, surgical tools, electric saws in open-brain surgery treatment;
