The Difference between PMSM & BLDC Motor

28 The Difference between PMSM & BLDC Motor • The Torque is a function of current and Back EMF - E bemf – E bemf is a function of how the stator has been wound • PMSM: stator with distributed windings will have a sinusoidal E bemf – In order to achieve constant torque we inject a sinusoidal current • BLDC: stator with concentrated windings will have a trapezoidal E
