Hello,

is there anybody who can give me some hints (or more

) for a design of a 1-phase BLDC Motor? (yes, 1-phase)

I need a very low noise control.

The current solution ist running with a triac. But the triac becames very loud if the motor runs slow.

App-Notes or something like that would be very helpfull.

Thx in advanced

Hello,

for me it isn't clear how a triac can be used for controlling a BLDC motor. Generally this switch is used when we deal with AC motor or universal motor. I would appreciate more details about your system, i.e., the architecture of your driver (micro or not?) and the type of motor (application field, size, power, etc.).

Regards,
