Application
The Brushless DC Motor is a permanent magnet motor with a trapezoidal back-EMF, as opposed to the sinusoidal back-EMF found in a permanent-magnet synchronous motor. The trapezoidal waveforms of a three-phase BLDC. In every commutation step, one phase winding is connected to a positive supply voltage, one phase winding is connected to a negative supply voltage, and one phase is floating. The zero crossings of phase back EMFs are indicated by ZC. The zero crossing occurs directly in the middle of two commutations.
At a constant speed, or a slowly varying speed, the time period from one commutation to zero-crossing and the time period from zero-crossing to the next commutation are equal which is used as basis for the implementation of sensorless-commutation control. The floating phase, where the zero crossing must be detected, changes for every commutation step.
One ADC channel for each phase winding is needed to detect zero crossings. The sensorless commutation method has challenges during startup or at very low speeds.A common method is to use excite the winding with a random start up commutation. A table of inter-commutation delays for the first few commutations is stored in flash. This sequence is executed without attention to the back-EMF feedback. The control is then passed over to the sensorless commutation controller.
Working of the BLDC Motor
The starting-current setup in the circuit through the stator windings sets up a magnetomotive force (mmf) which is perpendicular to the main mmf set up by the permanent magnet. According to Fleming’s left-hand rule, a force is experienced by the armature conductors. As the armature conductors are in the stator, a reactive force develops a torque in the rotor. When this torque is more than the load torque and frictional torque, the motor begins rotating.
The process of removing current from one circuit and giving it to another circuit is known as commutation.
The phase current and developed torque in the BLDC motor. In every case there are two phases that are contributing to positive torque and one phase contributing to zero torque. If the torque of each commutation interval is combined, the total torque is a contribution of two torques from two phases that are perfectly flat.
