Types of DC Motors level 3's

What are the 3 types of DC motors?

• Series motors, Parallel motors, and Compound motors

• Series motors, Shunt motors, and Complex motors

• Series motors, Shunt motors, and Compound motors

• Series motors, Shunt motors, and Conductor motors

What is another name for Series motors?

• Parallel motors

• Universal motors

• Compound motors

• Shunt motors

Why are Series motors suitable for loads that require full force immediately?

• Because they have low starting torques

• Because they can only work with AC

• Because they have high starting torques

• Because they cannot reverse the direction of the motor

How can the direction of a Series motor be controlled?

• By reversing the current flow on the armature only

• By reversing the current flow on the field windings only

• By reversing the current flow on either the field windings or the armature, but not both

• By using a variable resistor

What is used to control the speed of a Series motor?

• A fixed resistor

• A variable capacitor

• A shunt field regulator

• A variable resistor

What is a characteristic of shunt motors regarding starting torque?

• High starting torque

• Low starting torque

• No starting torque

• Variable starting torque

How is speed control achieved in shunt motors?

• By controlling the armature current only

• By controlling the field winding current only

• By controlling both the field winding and armature current independently

• Speed control is not possible in shunt motors

How can the direction of a series motor be reversed?

• By reversing the current flow on the field windings only

• By reversing the current flow on the armature only

• By reversing the current flow on either the field windings or the armature

• The voltage supply

What is a characteristic of compound motors in DC Motors?

• High starting torque

• No speed control

• Low starting torque

• Cannot control the direction

How is speed control achieved in compound motors of DC Motors?

• By controlling the armature current only

• By controlling the field winding current only

• Because the field winding and armature current can be controlled independently

• Speed control is not possible in compound motors
