The atmospheric environment does not produce strong magnetism, no corrosion,no explosive gas, no oil mist, no dust; the altitude is below 1000 meters.

Direct drives need high-quality position signals to ensure optimal performance. Perfect measuring signals can enhance the surface quality of machined workpieces, reduce the machine frame's vibrations, minimize velocity-dependent motor noise, and prevent excessive heat generation in the motor.


Mosrac recommends using a magnetic encoder to enhance the accuracy, speed stability, and thermal behavior of direct drive axes. Because there is no mechanical transmission between the encoder and the feed unit, the position signals are not susceptible to inaccuracies or delays.

Custom combinations are available on request and contact us.
