Lenze MCS L-force synchronous servo motors

Meeting stringent requirements in terms of response, precision and excellent power-to-size ratio.

The motor sizes have been carefully graded and offer rated torques from 0.8 to 64 Nm (0.25 to 10.0 kW) and peak torques of up to 191 Nm. As a result, finding the optimum motor for any drive task is easy.

What are detent torques?

Detent torques (reluctance torques, cogging) superimpose themselves on the electromagnetic torque, taking the form of a disturbance variable. This makes it harder for sudden changes in torque to be absorbed, results in increased system deviations when changing setpoints and makes it more difficult to compensate for speed variations. A detent torque of just 3% of the rated motor torque, for example, will reduce the potential control loop gain by 14%. Detent torques are caused by a lack of compatibility between the rotor-mounted permanent magnets and the workings of the stator lamination. In the case of MCS servo motors, which feature single element pole technology, magnetic attraction is optimised thanks to the special pole design. These motors exhibit extremely low detent torques, thereby providing maximum control loop gain for a stable control response, even within the context of high-response applications.

    – The shafts, which are made from high-strength steel
    – The vibration-resistant and fully-encapsulated windings
    – The robust connectors, which can rotate about 270°
    – The corrosion-resistant (NdFeB) permanent magnets

Generously proportioned bearings with high-temperature-resistant permanent lubrication ensure operational reliability even with a worst case scenario shaft load. The smooth surfaces and high degree of protection (IP54, IP65) make for quick and easy cleaning when required.
