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 customers demand.
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 customers demand.
Having recently introduced the EC-max premium range of brushless (electronically commutated) DC motors, which took performance to new levels, Maxon has now gone much further.
Its new EC-powermax 30 will deliver a 200W constant output - compared with the 60W rating of its 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The lozenge-shaped knitted coil normally expected in a high-powered EC motor has been replaced by a multilayer winding very similar to those used in Maxon's mechanically commutated drives.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.
It provides excellent control characteristics, particularly for positioning tasks, and is much quieter at high speeds thanks to the reduction in mechanical vibration.
The stationary winding surrounds a powerful rotating four-pole magnet, equipped with neodymium magnetic material, which replaces the two-pole rotor of the EC-max.
To cope with the extra stresses, the motor has a thicker body, the motor shaft diameter has been increased from 4 to 5mm, larger ball bearings have been used and the number of parts has been reduced.
The result is a highly durable and reliable unit with a torque capacity four times better than the powerful EC-max 30.
Like any EC motor, its inherent advantages include almost unlimited life, smooth performance, a very broad speed range and the ability to achieve high speeds even at low voltages.
To those benefits the Maxon EC-max range added extra dynamism, lower inductance and higher efficiency.
And now the Maxon EC-powermax 30 has taken that technology further still.
For even greater versatility, the EC-powermax 30 can be combined in Maxon's modular system with 42mm planetary gearheads, digital encoders (up to 1000 pulse) and brakes.
In conjunction with Maxon's DES (digital EC servoamplifier) controllers or intelligent positioning units (such as the new EPOS), it forms unbeatably high-powered, dynamic drive systems.
"EC-powermax 30 is ideal for applications requiring high torque at low speeds - in robotics or in actuators, for example", says Keith Ellenden, CEO of Maxon Motor UK.
"As well as its exceptional power to weight ratio, it comes with all the build quality and reliability you'd expect from Maxon - and its price is very competitive too".
