More power from small motor
March 1st 2006 The latest challenge for maxon motor has been to squeeze more power out of a small motor without sacrificing any of the reliability and efficiency that customers demand.
Having recently introduced the EC-max premium range of brushless (electronically commutated) DC motors, the company has now added the ECpowermax 30 which will deliver a 200W contact output, compared to the 60W rating of its correspondingly sized EC-max 30.
The motor measures just 30mm in diameter and weighs 270g. The lozengeshaped knitted coil normally expected in a high-powered EC motor has been replaced by a multi-layer winding similar to those used in maxon's mechanically commutated drives. This forms a grooveless stator, with no air gaps, that ensures efficient operation. It is said to provide excellent control, particularly for positioning tasks, and is quieter at high speeds due to a reduction in mechanical vibration. More articles from Maxon Europe Ltd.: |
