Which motor is preferred for jaw crushers?

2. Which motor is preferred for Jaw crushers? Explanation: Belt slip ring IM is preferred for the operation of Jaw crushers.

What is shunt wound DC motor?

A DC shunt motor (also known as a shunt wound DC motor) is a type of self-excited DC motor where the field windings are shunted to or are connected in parallel to the armature winding of the motor. Since they are connected in parallel, the armature and field windings are exposed to the same supply voltage.

How can the speed of a DC motor be controlled?

Thus, the speed of a DC motor can control in three ways: By varying the flux, and by varying the current through field winding. By varying the armature voltage, and the armature resistance.

Which electromagnet is preferred for noiseless operation?

Electromagnets are made of coils of wire called as solenoids. DC Motor Pros: It is capable of providing the high starting torque. DC motor allows smooth quiet control over a wide range of speeds.

How is speed of BLDC motor controlled?

Speed of a brushless dc motor can be controlled by controlling the input dc voltage / current. The higher the voltage more is the speed. Many different control algorithms have been used to provide control of BLDC motors. The motor voltage is controlled using a power transistor operating as a linear voltage regulator.
