Whats the best software to build a motor driver circuit?

I'm trying to build a schematic for a motor driver. I've been looking on PSpice, LTSpice, and Simulink/Simscape and can't find a part for a peristaltic pump anywhere. Any suggestions?? Any have any links to a library with pumps?

It depends on what type of motor is in the peristaltic pump.
Usually a brushed DC motor, that would be all you would need to use in your simulation.

Can you post the specs of your pump please?

Thanks.. Tom... :smiley: :+1: :coffee: :australia:

Hi! Here's the link for the pump, it's a 12V DC motor

I'm not familiar with simulations, but the spec so on that motor are;
12V 400mA

You would either find a MOTOR sim component, or just use a 12 / 0.4 = 30R resistor.
A resistor will not have the same exact characteristic as the motor, as there is start current and other dynamic parameters to account for.

You can use relays or triodes (power PNP/NPN) to control the power sent to the motor.

The motor says 12V 400mA but if you think it is spinning too fast (or too loud or etc) you can use a lower voltage (e.g. 9v)

To send signals to the relay/triode you can use arduino (automation) or a analog potentiometer/switch.
