PTC Temperature Sensor
The L-417.xx9211E1 is equipped with a PTC temperature sensor to prevent the motor from
overheating. The electrical resistance of the PTC temperature sensor increases considerably
into the critical temperature range. The controller must cut the power supply to the motor
(switching threshold) when the critical temperature is reached.
Temperature
Electrical resistance
Up to 150°C
< 550 Ω
155°C (critical temperature)
1000 Ω (switching threshold)
More than 155°C
> 1330 Ω

Commutation Encoder
The L-417.xx9211E1's motor has a commutation encoder that codes the position of the
magnets in the same way as a Hall effect sensor.
