7.3 PAPER MOTOR
Electrical phase resistance 3.8 Ω ± 10% measured at 25°C.
Phase inductance 11 mH ± 20%
Measured at 1 KHz, 100 mVpp with energized coil. Each coil should be within tolerance range, independently of the
detent position.
Rated motor voltage 3.85 V
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 0.42 A
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 B
Insulation classification is in accordance with IEC publication 85, the coils maximum temperature is 120°C.
Coil temperature is measured using the resistance method.
Insulation Resistance 100 MΩ with 550 Vdc.
Insulation Voltage 500 Vac. 1 minute
