Increasing miniaturisation in medical technology, optimised function and quality requirements are all enhancing the demand for advanced products. 

Maxon Motor has responded to this trend by offering a wide range of sterilisable motors and gearheads.

Traditional compressed air drives used in medical technology are gradually being replaced by electrical ones. They are more flexible to use, easy to regulate, more hygienic and not least, do not make the shrill noise that terrifies so many patients.

Electrical drives open up new possibilities for dental and medical technology. They can be used in a range of applications, such as handtools for surgery and dental medicine, infusion pumps, endoscopes, dialysis systems, collimators in radiation and analysis equipment.

As well as being completely reliable, one crucial aspect for medical applications - and one that has been a major problem for drives - is that the components can be sterilised.

Versatile drive solutions with sterilisable DC motors
Maxon Motor now offers three sterilisable, electronically commutated DC motors in diameters of 6, 16 and 22mm. The production processes and choice of material are specifically optimised for the extreme conditions of sterilisation.

The new sterilisable EC 16 with 40 watt output has a 12.6mNm torque and reaches speeds of up to 50’000rpm-1. The motors are available with integrated Hall sensors, helping create highly dynamic servo drives when combined with the appropriate electronics.

More torque with sterilisable gearheads
Gears can be used if greater torque and lower speeds are required. Maxon Motor is now adding a sterilisable 22mm diameter gearhead to complement its existing 6 and 8mm ones.

The new GP 22M has 55 different reduction ratios from 3.8:1 to 4592:1 and a maximum continuous torque of up to 2Nm. When combined with the sterilisable EC 22 motor, this creates a dynamic 50W unit that can be used in many applications. A 22mm diameter makes it ideal for handtools.
