Hi Nick? and All,
? ? ? ? ?? Yes this happens and is in the motor.? But not a problem. ?? The series? motor seems to get stuck in high power/torque? mode when accelerating and pulling a lot of power.
? ? ? ? ?? I was very happy when I found out by letting off power, then power on again and amps dropped by a lot for the same speed.? So I just do that for the last 26 yrs.
? ? ? ? ? ? ? ? ? ?? Jerry Dycus

I have had this happen alot in my car. It has a d&d motor 48v and an altrax axe controller. The wiring is all new in the whole car. It uses the stock forward reverse contractor. Sometimes when I hit the accelerator it will make a sound like a kazoo and the harder you press the louder it gets. I let off the accelerator and lightly get back on. This almost always stops this whine from continuing. It has been doing this for a? thousand miles or so. I am not experiencing and problems but I am not sure what it could be. The controller is 600a and I have a 400a slow blow fuse attached to it. Any ideas what could make this noise. It is not terribly loud but you can hear it about the volume of someone talking quietly.?
