Slow start motor control

WebbWe will connect an ultrasonic distance sensor in the place of the potentiometer, and use that to control the rotational speed of the motors. The idea is this: The distance sensor will tell the Arduino how close it is to an obstacle. If it gets too close, it will start slowing down the motors, effectively slowing down our prototype vehicle. Allowing a motor to start slowly creates several major advantages for the system and the bottom line. Reducing the motor’s initial driving force will lower the torque applied to components, increasing the lifespan of shafts, bearings, gears, couplings, etc. Another reason to increase the time for startup is to reduce in-rush current to the motor.

Webb3 okt. 2024 · If a small induction motor has a non-linear load, such as a fan, you can somewhat control the motor speed by reducing the motor voltage. In that case the motor no longer has sufficient torque to maintain its speed and starts operating at a lower speed, with a large amount of slip between the synchronous speed and the actual speed.
