commutation control cabinet for zircon in iran

what is commutation and how does it affect linear motor performance?

aug 8 in brushed motors commutation is easy to understand as brushes contact a commutator and switch the current as the motor moves brushless technology has no moving contacting parts and therefore is more reliable however the electronics required to control the current in the motor are a little more

bldc motor control algorithms renesas electronics america

trapezoidal commutation is inadequate to provide smooth and precise motor control of brushless dc motors particularly at low speeds sinusoidal commutation solves this problem this is because the torque produced in a three phase brushless motor with a sine wave back-emf is defined by the following equation
