    Suggestion for DC motor

    Hi everyone here!
    I am looking for a DC motor which has to run in velocity mode(no feedback control is required) at aprox. 2000 to 3000 rpm.
    I have searched a lot to select motor type for that purpose.
    I wish to use BLDC but it needs 3 phase control and PMDC has brush to maintain.
    Any body suggest me a good alternate for this.
    My requirement is as under:
    90 to 100 Watt, DC motor upto 24 volt, 2000 to 3000 rpm w/o closed loop control.
    Regards!

    Do you want single phase Brushless DC motor?
    Are you sure it doesn't come in single phase?

    Re: Suggestion for DC motor

    If you need a motor that has some torque at lower speed, a usual BLDC with 3 phase positional sensors is optimal. The effort isn't too high, the electronics fits in the motor housing. But also an asnchronous two or three phase motor with a variable frequency drive could be used. It's start-up torque is lower than with the BLDC but may be sufficient for many applications.
