I am surprised on the performance at low RPM, by the sound of that the motor is exhibiting it appears to be a SCR bridge version.
The PWM versions are whisper quiet, and I can control them down to zero rpm.

awesome I'll have to find a PWM version one day. I mainly went with this one because of that threaded end of the shaft. That's something I can work with... not sure if others have the same thing just hidden under that wheel thing. I would definitely like to have it full control.

What does the threaded shaft have to do with the controller?
By PWM I was referring to the controller, not the motor.
As to the reason for the threaded shaft is that is where the flywheel is mounted to, also why most T.M. motors specify unidirectional if the flywheel is retained.

In post # 60, indicates reversible operation. Is this your requirement? TM motors may not be reversible.

Usually only due to where a flywheel is threaded on!

Surplus Center catalog shows 19 TM Icon motors, all " reversible rotation ", most with flywheels & threaded shafts.

 

I would guess they have never powered them up at full rpm in 'reverse' with a flywheel attached, quite the spectacle, they usually weigh in at close to 20lb.

Imagine the counter-shock! ... I bet they're first braked by shortening their leads through a resistor before applying reverse power.

In their normal environment of T.M. platform, they never have to reverse.
The controllers themselves are also Unidirectional.
