Thanks.This is not a servo motor.
This is a single phase AC induction motor. It will not start without a capacitor.
Why single-phase induction motors need capacitors?
Password and authentication needed for the link?You might find this useful: ITEM # RHT6P4N-25, RHT SERIES REVERSIBLE MOTOR WITH TACHOGENERATOR & SPEED CONTROL. It seems to cover your motor as used with a controller.
Thanks.If it is a PSC motor, where both windings are identical, then all that is needed to reverse is a SPDT SW with centre off, you could also do it with a SPDT relay, but a means of OFF would be needed also.
Generally a Triac based control is used.
I doubt if a fraction of the electronics shown were to control the motor.
Not sure what that sensor? is on the back of the motor, only two leads?
What the? There was a PDF there. I see what I did, I started here:Password and authentication needed for the link?
The only other motor it could be is a mains operated stepper motor, (Synchronous).
But this would not require any electronics.
Thanks,The labe tells us what it is: It is indeed a reversible induction motor with a 3 microfarad capacitor phase shifter. Mains neutral would tie to the white wire, and then the line voltage will connect to one of tjhe motor wires tjhat go to the capacitor ends. Which end defines which direction it rotates.
The alternative to using the capacitor to make it run is a fairly complicated bunch of electronics that require a power supply and an analog control signal.
Thanks.This is the controller shown in the drawings:
There is also an additional drawing:
All I see mention of is tachometer output and while we know it's the gray wires we don't know what the actual signal out is. Since it is just two wires and they are both the same color it likely could be an AC signal but unless what it is is known it's impossible to suggest any signal conditioning to get it to where and Arduino or any uC can read it. A scope would be nice to have about now.
Thanks for the further information.The motor resembles both a PSC AC induction motor and a Synchronous AC stepper motor, the difference can easily be determined but spinning the shaft, the Induction motor will spin free, the stepper will present 'bumps' as it is turned.
Both of which only require a mains AC supply to operate.
Thanks.You can try measuring the voltage on those two gray wires while manually spinning the motor by hand, or wih a variable speed drill motor. Because they are the same color it must be an AC tach generator.
Thanks.If there is no control of the motor, the tach would just be used for a rpm indication, IOW, not used in a controlled loop.
A tach cannot be used for position indication like an encoder can, just rpm rate.
