Global Small DC motors in Automotive Applications

Date: 2016-09-12

Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools, appliances, and automotive. 

Automotive applications like air-conditioner valves, door mirrors, and windows need small, power-conscious motors.

The smaller package size contributes to the miniaturization of printed circuit boards (PCBs) for a savings in board real estate. The devices also integrate circuits to detect faults, such as over-voltage and over-current conditions, and report them to a host microcontroller.

The brushed DC electric motor generates torque directly from DC power supplied to the motor by using internal commutation, stationary magnets (permanent or electromagnets), and rotating electrical magnets.
Advantages of a brushed DC motor include low initial cost, high reliability, and simple control of motor speed. Disadvantages are high maintenance and low life-span for high intensity uses. 

Typical brushless DC motors use one or more permanent magnets in the rotor and electromagnets on the motor housing for the stator.
Advantages of brushless motors include long life span, little or no maintenance, and high efficiency. Disadvantages include high initial cost, and more complicated motor speed controllers.
