Hi guys im looking for idea on how to control a 24V dc motor, looking at around 30W, its a small motor from one of the pumps in my saltwater reef tank, it comes with a controller but im not happy and i want to build my own to pulse the pump, i want it to sort of run on
2v for and then ramp up to 24v for about 2 seconds, its a wavemaker pump so in other words i want to pulse it, what do i need and how do i do abut doing this, also how can i vary the duty cycle? i was thinking some sort of timer circuit and an FET to control the votage to the motor. how do i go about doing this?
