circuit design for stepper motor driver

$30-250 USD

$30-250 USD

Paid on delivery
I am looking for a fairly simple circuit that can drive a small (12 volt, 400mA) stepper motor at a specific constant speed. This is for a timekeeping/clock application, so accurate timing is essential. The circuit must also incorporate a momentary switch which will run the motor at a higher rate of speed, for setting the clock. A directional control would be welcomed as well. Power supply is up to the designer, but something in the 6~12 VDC range would be preferred. This would be a low-volume project, starting with 10 units, after confirming that a prototype is acceptable.

The power supply for the circuit should be chosen for the voltage of the stepper motor you want to use. Also, there are more than one type of stepper motor. For example, uni-polar and bi-polar. And they require different circuits... The design should start with choosing the stepper motor or range of stepper motors you want to use. I would recommend a small micro-controller to control the output stage so that you can get your accurate timing and other features you need. I can design and build a prototype of this.
