Maxon Motor has developed an electrically commutated motor.

The EC 25 High Speed has been designed to produce the highest possible speed for a motor of its size with virtually no vibration and, in doing so, achieved over 93 per cent efficiency.

Despite its 25mm diameter, the brushless motor runs at speeds of over 60,000rpm with almost no vibration characteristic and delivers 42.2mNm of torque at a speed/torque gradient of 44.0rpm/mNm.

This speed and size-to-power ratio means the EC 25 could create possibilities in precise, spindle-driven applications requiring high performance in a compact space, such as in medical instruments and surgical power tools, or the machine tools used in the manufacture of optical lenses.

This combination is maintained by means of preloaded ball bearings, high-precision balancing and a two-pole Neodymium permanent magnet.

The stranded-wire winding and the magnetic return make the most of the EC 25’s 250W output.

It is also modifiable to meet individual requirements.
