Is it possible to make a 3-phase electric motor variable speed? - posted in Electrical: Hey guys, before we call some sparkys and get taken for a ride (well we already called one and he made it seem way overcomplicated) We have a 3-phase motor running a fan for the spray booth but for some instances it is too powerful and creates too much flow.... If it is a DC motor then your existing circuit is correct, but the mosfet is still not correct, because 2.5 amp is not sufficient for your motor, so make sure to use a mosfet which is rated at minimum 10 amps, which should hopefully solve your problem. You can try IRF840 for the mosfet.

23/11/2014 · Treadmills use DC motors which are easier to speed control than AC motors and used treadmills can be had relatively cheap. Components to the system are the DC motor, motor controller (PWM), potentiometer (pot), switch, fuse, and usually a choke (transformer)....
Armature terminal voltage control: The speed control of DC series motor can be accomplished by supplying the power to the motor from a separate variable voltage supply. This method involves high cost so it rarely used. Field Control of DC Series Motor The speed of DC motor can be controlled by this method by any one of the following ways – Field Diverter Method This method uses a diverter

Having tried 500k, 10k and 500ohms, the motor stalled almost as soon as I turn the dial (a bit more leeway with the 500ohm but not much).. How to make a paramotor

24/08/2012 · i say, do not but for emergencies use variable potentiometers or variable transformers to control your DC motor load. the stall mode will cook your motor. the stall mode will cook your motor. with PWM, the motor will will have time during the off phase of the circuit to diffuse any generated heat.

  • An AC controller changes the frequency of the current to control the speed of the motor. Making DC. Motor controllers are usually supplied with AC power. The power that comes in to a controller is at a set frequency. The motor controller first turns that AC to DC, then turns the DC back into AC at the right frequency. It uses a device called a rectifier to make DC current. Inside the rectifier
