The universal motor is one type of electric motor which can operate on either AC or DC power and uses an electromagnet as its stator to create a magnetic field. This motor is commutated series would motors where the stator field coils are connected in series with the rotor winding through the use of a commutator. Here this posts five the information about the advantages and disadvantages of the universal motor to better understand this topic.
Advantages of a universal motor:
- It is a cheap motor.
- It can run from AC or DC supplies.
- It has good torque at low speed.
Disadvantages of a universal motor:
- Brushes and commutator wear out, create sparking which can cause electromagnetic interference and maybe an ignition source of VOCs.
- It is not easy to reverse the motor.
- Speed control is lousy.
- High maintenance cost and short life commutator caused by the commutator.
- Produce more noise and vibration than the induction motor.
