Singer 15-90 - Connecting and Basic Operation

4
Motor Can be Operated on Either Alternating
Current or Direct Current
The electric 'motor, which is located at the back
of the machine, can be operated on either alternat-
ing current or direct current, as desired. The
standard windings of the motor are for 110 volts,
and motors can be furnished for any voltage be-
tween 100 and 250.
Special motors for 32 volts direct current, and
for 50 volts alternating current and direct current,
have also been developed and are available.
Points to Determine Before Connecting
Motor to Electric Service Line
Obtain the following'information from the Elec-
tric Light Company which supplies the electric
current for the circuit to which the motor is to
be connected:
1.
If current is direct, what is the voltage? The
voltage must be within the range stamped on the
name plate of the motor.
2.
If current is alternating, in addition to the
voltage, what is the number of cycles? The number
of cycles must be within the range stamped on the
name plate of the motor.
The voltage of any circuit and, if alternating
current, the number of cycles, can be verified by
looking at the name plate on service watt meter
installed by the local Electric Light Company.
