Drive with more than 1,500 autoclave cycles

Faulhaber has developed a new sterilizable motor family, the 2057...BA series, which has been specially designed for medical applications. In the sensor-free version, the drives can withstand more than 1,500 autoclave cycles. They are optimized for speeds of up to 65,000 rpm.

The motors in the 2057...BA series are housed in a rustproof, moisture-resistant stainless steel housing. During development, they were tested for their resistance to the stresses of autoclaving. According to the company, these tests ensure that the standard motor can withstand a typical 1,000 cycles in the autoclave without damage. For the sensor-free version, this value is 1,500 cycles.

Autoclavable motors are often used in the handpieces of dental or surgical hand instruments. Very high speeds are generally required there. The 2057...BA series achieves a speed of up to 65,000 rpm. Other applications for this type of motor can be found in other areas of medical care, such as ventilators. According to Faulhaber, the motors in this series are also characterized by high performance values in relation to their volume. They are therefore suitable for confined installation situations. Their low weight makes them ideal for use in handpieces, which are often used for delicate work over many hours.
