PWM inverter for 12 VDC motor

Hello everybody!
I have 12VDC spindle motor. Can you point me to a good PWM inverter which can be controlled by Mach3 (speed an direction)?
Thank you in advance

If you have a 12VDC motor you don't need an inverter (which converts DC to AC). You need to look for a speed controller that will drive a 12VDC motor.

Thank you Jeff ,
I'm sorry, this is terminology mistake. Yes I'm looking for a speed controller which drives 12VDC motor and controlled by PWM impulses generated by Mach3
I'm looking for a diagram or something from the shelf.
Best regards

The Homan Digi-Speed board converts the Mach PWM signal into an analog reference voltage, you still need a speed controller. A quick search turned up this:

Never used on of them though, but it might give you an idea of what to look for.
