BLDC motor

sasi sunkara

Is a driver mandatory to connect a BLDC motor to AC power. Can we connect the motor with SMPS to AC power without a DC driver?

Step down from 230 Volt to 48 Volt ( DC)

Thank you

Hello Sasi,

Yes, you will need an an inverter (control & driver) to spin a BLDC motor. (This white paper may be insightful to compare single-phase ACIM to BLDC)

1) You can rectify 230V AC and drive the motor with a high-voltage inverter (i.e. a system like this EVM)

2) You can drop 230V AC to 48V DC and drive the motor with a low-voltage inverter (i.e. a system like this EVM)

Thanks,

Matt
