Dcs/ PDS motor

Hedger · 03-15-2017, 05:24 PM

Will my dcs motor AY4-4001 work in a PDS cart? I have a PDS that the motor whines real loud and am thinking I should replace the motor.

They use different field maps (which map the characteristics of the motor), so I would advise against it.

A DCS motor does not have a speed sensor and a stock PDS controller won't let the cart go over about 2 MPH without a working speed sensor attached to it.

If you have an aftermarket controller like a DCX or XCT (with RPM limiting shut off), it will work, but the cart will be a bit slower and have i little more torque than it did with a PDS motor. Of course, the correct field map will have to be loaded.

This motor does have a speed sensor.

Ok, help me out here. I have a motor that is real loud, at least I think it's the motor and not the rear end. Is there something I can do to quiet the motor or am I in the market for a different motor. I have the dcs motor. Do I try to fix, motor, buy another or use the dcs and buy control?

I have a DCS running a DCX 500a controller, no speed sensor. The cart clocks about 21.5-22mph verified by Garmin GPS, with windshield down, one person txt cart with a back seat, 18inch tires

Cheapest thing to do, if you have the skills, is to change the bearing ($6-

Next step up would be to have somebody else change the bearing and paint it $300. Or buy a new motor $4-500

Also note the noise may be coming from the input shaft and not the motor. Although my old PDS motor was starting to whine when I pulled it out.

may look at changing the bearings. I usually realize I don't have the skills about half way through the the job. Don't guess there's a sticky on it?

Last question on this. Can I put another motor in cart and do the 12 volt test on that motor to see if it's the input shaft or the motor? Seems that if the test ran quiet, it would have to be the motor? It currently whines loud at low speed even with wheels off the ground.

Sounds like you should just take the pan off the axle, drain the oil & have a look for metal. I bet it could use new oil anyway. It's a easy job. You could swap a motor on there to see a 12v test. That will give you a chance to see how badly neglected the input shaft/motor coupler spline interface is (and is a rubber bumper present).
