Controller
The controller is very complex and expensive, it can control the timing of switching the current to
the poles in stator.
For
this Switched Reluctance motor, the rated output is 0.87KW, and it’s a
four-phase motor, so it has four pairs of electric wires. The rated speed is
6000 rpm, rated voltage is 48 VDC. They have simple and rugged construction, an
extremely long constant-power range and high-speed operation. Since SRM control
involves successive excitation of poles to align the rotor, torque ripple, vibration
and associated acoustic noise are the main concerns in SRM operation. They require
a complex converter topology for the drive that makes their control complex and
expensive.
