Question 1

Four-speed consequent pole motors have two windings.&#10;A)dual&#10;B)field&#10;C)reconnectable&#10;D)programmable

Accepted Answer

Consequent pole motors have two reconnectable windings, which allow for the change in the number of poles and thus the speed of the motor by reconfiguring the connections of the windings.

Question 2

Three-speed, consequent pole motors have three windings.

Accepted Answer

Three-speed, consequent pole motors have two windings, not three. The speed variation is achieved by changing the number of magnetic poles, not by adding more windings.

Question 3

Circuits for controlling a two speed consequent pole motor may use contactors with three load contacts because they are more ____.&#10;A)eco-friendly&#10;B)readily available&#10;C)economical&#10;D)spacious

Accepted Answer

B

Question 4

Machines will not be harmed if the direction of rotation is changed from that for which they are designed.

Accepted Answer

Machines are designed to operate in a specific direction of rotation, and changing the direction of rotation can cause damage to the machine or its components. Changing the direction of rotation for a machine can cause harm or damage to the machine and may also affect its performance. Therefore, it is important to follow the manufacturer's instructions and use the machine as it is intended to be used.

Question 5

A three-phase squirrel cage motor can be wound so that six leads are brought out.

Accepted Answer

A three-phase squirrel cage motor can be wound so that six leads are brought out, typically labeled as U1, V1, W1, U2, V2, and W2. These extra leads allow for different wiring configurations to achieve various voltages and speeds. A three-phase squirrel cage motor can be wound so that six leads are brought out for connection to a delta or wye configuration.

Question 6

The fewer the number of poles established in the stator, the greater is the speed in of the rotor.&#10;A)cycles per minute&#10;B)phases per minute&#10;C)revolutions per minute&#10;D)trips per minute

Accepted Answer

The speed of the rotor is directly related to the number of poles established in the stator. The fewer the number of poles, the greater the speed in revolutions per minute (RPM). The speed of the rotor is directly proportional to the frequency of the power supply and inversely proportional to the number of poles established in the stator. Therefore, fewer poles will result in a higher speed in revolutions per minute (RPM) of the rotor.

Question 7

Two-speed, consequent pole motors have one reconnectable winding.

Accepted Answer

Two-speed, consequent pole motors have one winding that can be reconnected to switch between the two speeds. Two-speed, consequent pole motors have one winding that can be reconnected in different configurations to achieve different speeds.

Question 8

In a two speed, reversing controller, the circuit may provide automatic acceleration to high speed in either the forward or reverse direction.

Accepted Answer

A two speed, reversing controller can provide automatic acceleration to high speed in either the forward or reverse direction. A two speed, reversing controller typically has settings for low speed and high speed in both forward and reverse directions. The circuit can provide automatic acceleration to high speed in either direction, depending on the user's input. This feature is designed to improve the overall performance of the motor and provide greater control over its speed and direction.

Question 9

The correct rotational direction is indicated by on the driven machine.&#10;A)arrows&#10;B)labels&#10;C)braille-type dots&#10;D)tags

Accepted Answer

Arrows are commonly used to indicate the correct rotational direction on a driven machine. This is important information to ensure that the machine operates correctly and efficiently, and to avoid any damage or safety hazards. Labels, braille-type dots, and tags may also be used for other types of identification or warning, but arrows are the most appropriate for rotational direction. Arrows are commonly used to indicate the correct rotational direction on driven machinery. They provide a clear visual cue for operators to ensure that the machine is running in the correct direction, which is important for efficient operation and preventing damage. Labels, braille-type dots, and tags may also be used for other types of instructions or information, but arrows are most commonly used for directional indicators.

Question 10

In a two speed, reversing controller, an overload in either the low or high speed setting will de-energize the .&#10;A)stator&#10;B)contactor&#10;C)rotor&#10;D)control circuit

Accepted Answer

An overload in a two-speed, reversing controller will de-energize the control circuit to protect the motor from damage.
