FAULHABER 2057…BA sterilisable motors

Click2Contact

FAULHABER developed the sterilisable 2057…BA family of motors especially for medical applications. In the sensor-free variant, the drives can withstand more than 1500 autoclave cycles. They are optimised for high speeds of up to 65,000 rpm, as are required in, eg, the handpieces of dental equipment.

The motors are fitted in a moisture-resistant, stainless steel housing. During the development process, they were thoroughly tested for resistance to the loads experienced during autoclaving. These tests indicated that the standard motor can typically withstand 1000 cycles in the autoclave undamaged. For the sensor-free variant, this value is 1500 cycles.

Autoclavable motors are frequently used in the handpieces of dental or surgical handheld instruments, which generally require very high speeds. Further applications for this motor type are found in other areas of medical care, such as in ventilators.

The motors are characterised by high power values in relation to their volume, making them useful for tight installation situations. Their low weight also makes them suitable for use in the handpieces with which doctors and dentists perform delicate tasks, often over several hours.
