Motor Can be Operated on Either Alternating

Current or Direct Current

The electric motor, which is built in Machines

101-4 and 101-12, can be operated on either direct

current or 25 to 75 cycle alternating current without

change of adjustment. The standard windings of

the motor are for 110-120 volts, but motors can also

be furnished for any voltage between 50 and 250.

Special motors for 32 volts direct current and

above 75 cycle alternating current have also been

developed and are available.

Points to Determine Before Connecting

Motor to Electric Service Line

Obtain the following information from the Electric

Light Company which supplies the electric current

for the circuit to which the motor is to be connected:

1. Whether alternating current or direct current

is used.

2. What is the voltage? The voltage must be

within the range stamped on the motor name plate

(B, Fig. 2, page 5).

3. If the electric service line is alternating current,

what is the number of cycles? The number of cycles

must be within the range stamped on the motor

name plate.

4. The current and voltage of the electric service

line and, if alternating current, the number of cycles,

can be verified by looking at the name plate on

electric meter installed by the local Electric Light

Company.
