New 50-W versions boost surgical uses for Maxon’s sterilisable motors

Maxon motor has expanded its range of sterilisable drives for high-speed medical applications with the introduction of the new 50 W versions of its EC 13 and EC Size 5 brushless motors.

Both drives, produced in accordance with Medical Standard ISO 13485, offer high performance with extremely low noise and vibration, generating very little heat and making them ideal for medical use.

The upgraded 50 W versions offer speeds of up to 90,000 rpm with efficiencies now reaching 90 percent, whilst delivering 50 percent more torque at 8 m Nm when compared to the standard 30-W drive.

This additional performance is provided with only 11 mm of extra length, making the new 50-W drives particularly suitable for a range of surgical procedures where there is a need for increased power in confined spaces.

The highly versatile motors are available with or without Hall sensors and come with 12- 24- or 48- V windings.

Thanks to Maxon’s unique design the motors can be sterilised up to 500 times in an autoclave without any need to dismantle, opening new avenues for surgical equipment designers.

Maxon Motor UK Senior Sales Engineer Ian Bell said: “With a very high nominal speed, quiet running, minimized heat generation and the ability to be sterilised in an autoclave, the 50 Watt drives offer new possibilities for medical use where a compact design is necessary.”
