Question

If it is necessary to reverse the direction of a DC motor, the simplest way to do it is to __________. a. reverse the armature leads b. reverse the polarity of the power supply leads c. add a capacitor between the positive and negative DC voltage leads d. get a reversed wired DC motor 2. In a shunt configured DC motor, the series field is ____________. a. attached in series with the shunt field of the motor b. connected in parallel to the shunt field of the motor c. disconnected from the motor d. shorted out (shunted) to prevent counter EMF 3. In a series configured DC motor, the series field is __________. a. attached in series with the armature of the motor b. attached in series with the shunt field of the motor c. connected in parallel to the shunt field of the motor

Answer 1

1. A - reverse the armature leads

2. B - attached in parallel to the shunt field of the motor

3. A - attached in series with the armature of the motor

Step-by-step explanation:

1. The simplest way to reverse the direction of a DC motor is to change the armature terminals (leads) or alternatively, to change the field terminals (leads). However, only one of either the armature terminals or the field terminals must be changed; the two must not be changed at the same time.

Hence, option A is the right answer - reverse the armature leads

2. The shunt configured DC motor is a type of self-excited DC motor. In a shunt configured DC motor series, the armature winding is connected to the field windings in a parallel connection. of the motor connected in series with the shunt field of the motor.

The correct answer is option B - The series field is connected in parallel to the shunt field of the motor

3. The series configured DC motor is a type of self-excited DC motors. In a series configured DC motor, the armature winding is connected to the field windings in a series connection.

The correct answer is option A - The series field is connected in series with the armature of the motor.
