CARRIAGE MOTOR

Electrical phase resistance
Phase inductance
Measured at 1 KHz, 100 mVpp with energized coil. Each coil should be within the tolerance range, independently of
the detent position.
Rated motor voltage
With rated voltage applied to both phases (parallel), the coils reach the limit of insulation class with motor in air and
ambient temperatur 25°C.
Rated phase current
With rated phase current applied to both phases (parallel), the coils reach the limit of insulation class with motor in air
and ambient temperature 25°C.
Insulation Class
Insulation classification is in accordance with IEC publication 85, the coils maximum temperature is 120°C.
Coil temperature is measured using the resistance method.
