Description
hardware flow control. It is an ideal choice in the field of industrial automation.
The most fundamental reason for distinguishing these two motor types is that the
design of the air gap magnetic field is different. So the following differences arise
The back EMF waveform is different:
BLDC: Approximate trapezoidal wave (ideal state);
PMSM: sine wave (ideal state);
The three-phase current waveforms are different:
BLDC: Approximate square wave or trapezoidal wave (ideal state);
PMSM: sine wave (ideal state);
Differences in control systems:
BLDC: usually includes position controller, speed controller and current (torque) controller;
PMSM: Different control strategies will have different control systems;
Controls are different:
BLDC: 120-degree square wave current, using PWM control;
PMSM: Positive Xuan wave current, controlled by SPWM SVPWM.
However, in actual control, brushless DC can also be controlled by FOC, and permanent magnet
synchronous motors can also be controlled by square waves.
Just like the controllers of electric vehicles, I have disassembled and studied three or four. The interfaces are
all the same, the control chips are different, and of course the control algorithms are also different. Electric vehicles
controlled by sine waves have very low sound when starting and running, and there is no jitter during operation;
but electric vehicles controlled by square waves have very obvious sounds, and the jitter during operation can also
be felt. The judder is due to definite torque ripples.
Motors controlled by square waves have higher power efficiency, because motors controlled by sine waves have a lower effective voltage.
4. Control technology of permanent magnet synchronous motor
Permanent magnet synchronous motors and brushless DC motors can be operated using the same control method.
