Can a universal motor run on AC/DC or Both?

Yes, both AC (alternating current) and DC (direct current) power sources can be used to power a universal motor.

  • An electric motor that can run on either AC or DC power is known as a universal motor. It is referred to as “universal” because it may be utilised in a variety of applications with a wide range of power sources.

  • The stator (field winding) and rotor (armature winding) of a universal motor are both connected in series, similar to a series-wound DC motor. The motor can run on both AC and DC power with this arrangement.

  • The motor rotates continuously when it is connected to an AC power supply because the stator and rotor windings alternate in the direction of current flow. The motor’s speed is determined by the AC power’s frequency.

  • When plugged into a DC power source, the current passes through the stator and rotor windings in the same direction, which causes the motor to spin in the same direction. By changing the voltage delivered to the motor, one may regulate the speed of a DC motor.

  • It’s crucial to remember that, despite the fact that a universal motor can function on both AC and DC power, the performance characteristics and efficiency may vary depending on the power source

  • To ensure effective use of the universal motor with the desired power source, it is advised to refer to the manufacturer’s specifications and guidelines as the motor’s design and construction are optimized for certain operating conditions.
