High-speed brushless motor launched by Maxon
A
Maxon Motor UK product story
Edited by the Engineeringtalk editorial team
Jul 27, 2009
Maxon Motor has developed the EC 25 electrically commutated motor to produce high speed with virtually no vibration.
The company said the motor achieves more than 93 per cent efficiency, and sets a new benchmark in energy efficiency for off-the-shelf technology.
The EC 25 brushless motor runs at speeds of more than 60,000rpm with almost no vibration characteristic
Despite its size of 25mm in diameter, the brushless motor runs at speeds of more than 60,000rev/min with almost no vibration characteristic, and delivers 42.2mNm of torque at a speed/torque gradient of 44.0 rev/min/mNm.
This means the EC 25 could create new possibilities in precise, spindle-driven applications requiring extreme performance in a tiny space, but with absolute stability - 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 help the EC 25 make the most of its 250W output to deliver good results.
The EC 25 is modifiable to meet the user's individual requirements, ensuring its blend of performance and size has the potential to impact a wide variety of contexts.
