Abstract (en)
[origin: EP1172560A2] The feed device has a current-controlled electric motor, e.g. a servo or stepping motor and a conversion gearing, converting the motor rotation into a linear reciprocation for driving the feed device. The current for the motor is limited by the expected motor loading dependent on the stroke position of the feed device.
