Power boosted, quality maintained

Power boosted, quality maintained The latest challenge for Maxon Motor has been to squeeze even more power out of a small motor, without sacrificing any of the reliability, efficiency and other qualities that users demand. Having recently introduced the EC-max premium range of brushless DC motors, which tool performance to new levels, Maxon has now gone much further. Its new EC-powermax 30 will deliver a 200W constant output, compared to the 60W rating of the correspondingly sized EC-max 30. So how does Maxon pack so much power into a motor that measures just 30mm in diameter and weighs just 270g. The answer lies in a host of patented developments, starting with an ingenious new winding. The lozenge-shaped knitted coil normally expected in a high powered EC motor has been replaced by a multi-layer winding very similar to those used in maxon’s mechanically commutated drives. This forms a grooveless stator, with no air gaps, that ensures efficient, detent-free operation. To cope with the extra stresses, the motor has a thicker body, the motor shaft diameter has been increased from 4mm to 5mm, larger ball bearing have been used, and the number of parts has been reduced.
