An industrial low-voltage inverter for PRM control

The PRM which uses reluctance torque positively and reduced the amount of magnets relatively, and the industrial low-voltage inverter to which the PRM control function is applied has been developed. Though exact motor parameters may not be known, the inverter has a control method which on-site PMM control commissioning can be performed easily for such the case. The combination test of the PRM and the inverter was carried out, and each performance was checked.
