®
motors are
satisfactory for operation on 50 Hz power supplies at full rated
horsepower with no derating required. Durable self-adhesive
labels are available from your LEESON District Office for
affixing to the motors, if desired. These labels state the motor
is satisfactory for operation on 50 Hz. The speed of the motors
on 50 Hz will be approximately 5/6 of the 60 Hz speed noted
in this catalogue.
2EQUEST LABEL
4HIS LABEL SIGNIFIES THE MOTOR IS
satisfactory for 50 Hz voltages of 190-200-208-220 volts
when the “low voltage” connection is made. For the “high
voltage”connection the motor is satisfactory for operation on
380-400-416-440 volts, 50 Hz.
Other three phase motors may be operable at 50 Hz at 5/6ths of
60 Hz horsepower and speed. Check with LEESON to verify that
the motor is satisfactory for derated operation on 190-200-208
volts using the “low voltage” connection or 380-400-416 volts
USING THE hHIGH VOLTAGEv CONNECTION AS SHOWN ON LABEL
Applies only to steel frame motors.
