I have a project where I have to sweep a windshield wiper about 90° at a rate of 150 sweeps/minute. (~3 sweeps/second)
Since the sweep rate is high, I was thinking of using a stepper motor to get it done.
I will get the specs of the wiper soon after which I may be able to estimate the voltage,current and torque requirements.
But I need advice regarding the motor and driver choice since the project timeline is short and we cannot afford to make mistakes.
Edit: I'm a bit inclined towards a stepper motor due to it's speed and sweep controllability, though will it be able to accelerate and decelerate the load at such a high rate?
Edit: I realise that the windshield link mechanism to convert rotational motion into sweeping one would be a much better approach and a brushed DC motor would do the job nicely. So the only challenge remaining is getting enough torque and rpm out of it.
P.s I checked some wiper motors, they have 55 rpm with 40 kg-cm torque
