Iam trying to use a Power mosfet (IRL520) to control the
speed of a DC motor, i have setup 2.2v on the base of the
transistor. The source is connected to ground. I then put the 24v
to the positive of the motor and the return from the motor is attached
to the drain of the transistor.
When i power up the circuit, the motor starts and then continues to
speed up until the full 24v is dropped across the motor? Whay is this
and how can i stop it. The circuit is pretty similar to the circuits
you would see interfacind a motor to a PWM output.
Thanks
