BRUSHLESS SERVOMOTORS

Our servomotors use permanent magnet field excitation. This synchronous motor technology offers a number of operational advantages: 

• high dynamic response (high ratio of torque/inertia and peak/continuous torque)
• optimum power/weight ratio
• high efficiency
• smooth constant speed performance

Depending on the application, different mechanical versions are available:

• kits with hollow shaft for direct integration in the machine (e.g. MS, QB (Quantum) series)
• aluminium housings for light machinery applications in order to minimise weight and cost (e.g. QB, Quantum series)
• robust, industrial style housings with connectors (e.g. MS-, MP- or AKM-series)
• custom versions (e.g. MH series for high speed applications)

The brushless, synchronous motor needs to be electronically commutated. I.e, a sensor is needed on the shaft, which can report the absolute electrical angle of rotor to the controlling power electronics. Only then can the motor phases be energised correctly. Preferentially we use hall-effect sensors (for block commutation) or resolvers (for sine-wave commutation). The latter type of sensor can also be used for position feedback.

Our motors can also be operated at lower voltages than stated in the datasheets. The max. achievable operating speeds (no-load) drop however accordingly.
