Continuous power of the linear motor
When reducing the continuous torque, the electirc continuous
poweris also reduced
The maximum output is also the sum of the mechanical and electrical maxi‐
mum output. It must be made available to the drive during acceleration and
deceleration phase or for very high machining forces, for example.
