Autoclavable controllers for BLDC Slotted and Slotless sterilizable motors

Electronic commutation is needed to run BLDC motors. To drive a BLDC motor the mandatory requirement is the rotor position. This information is normally extracted from the Hall sensors or the encoders in the sensored controllerss. In the sensorless controllers, the rotor position is estimated by specific algorithms based on current and voltage feedback.There are 2 types of major commutations methods are used to run the BLDC motor - Six step commutation and sinusoidal commutation.

Autoclavability for controllers is a requirement in certain surgical handtool applications identfied by Portescap and hence Portescap's has designed autoclavable controllers that can withstand up to 1,000 sterilization cycles and are fully compatible with Portescap's SMS BLDC slotted and BLDC slotless range of sterilizable motors. These autoclavable controllers are perfectly suited to drive battery-powered surgical hand tools.
