A/An is used in domestic mixers?

• A. Permanent magnet synchronous motor
• B. Induction motor
• C. Universal motor
• D. Shaded pole motor

Answer: (C)

We use universal motors in mixer grinders. Universal motors can run both on a.c. and d.c.
The universal motor works on the same principle that DC series motor works. DC series motor has the characteristics of operating at high-speed when there is no load and operating at low-speed when the load is applied. It has high starting torque characteristics.
So it is used in mixers, where initially we put some load at starting.
