What is Universal Motor in car : Top manufacturers

A universal motor is a type of electric motor that can operate on both alternating current (AC) and direct current (DC) power supplies. In automotive applications, universal motors are commonly used in auxiliary systems such as windshield wipers, power tools, blowers and small actuators where high speed, compact size and strong starting torque are required. These motors are typically compact, efficient, reliable and designed for 12 V automotive electrical systems.

Understanding Universal Motors in Automotive Applications

In automotive terminology, the motors used for mirror, seat, and window control are generally:

  • Brushed DC motors (often loosely called “universal motors”)
  • Rated for 12 V DC
  • Integrated with gearboxes and actuators
  • Designed for high torque at low speed

They are not standalone consumer motors but automotive grade motors supplied by Tier-1 and Tier-2 manufacturers.

Key Automotive Applications of Universal Motors

  1. Power Window Control
  • Drives window regulator mechanisms
  • Requires high torque and durability
  • Typically used with worm gear or spur gear reduction
  1. Mirror Adjustment and Folding
  • Controls mirror glass movement (X/Y axis)
  • Powers mirror folding mechanisms
  • Compact size with precise control
  1. Power Seat Adjustment
  • Used for seat slide, recline, height and lumbar support
  • Requires higher torque and load handling
  • Often multiple motors per seat
