winch with motor

Good day,
i am building a motor driven winch. I want to speed control the motor. I also want to attach an electromagnetic brake to the motorshaft. If I want to lower different loads, I see the problem when opening the brake, the load will just fall down for a while until my controller has corrected the speed. Is there a motorchoice or controlstategy to avoid this behaviour, so that after releasing the brake, a desired velocity is possible.

Thanks

PID is the usual strategy to control motor speed, and it requires a means to measure the speed.

Most people use a shaft encoder or tachometer to measure the shaft rotational speed.

yeah that is correct. But my question is how to make sure while releasing the brake, that the motor is not pulled down by the load?

The motor WILL be "pulled down by the load". PID is used to control the speed of descent, possibly by back driving the motor. This is called active braking.

You could use a worm gear drive, which cannot be back driven by the load.

Or is it possible to use a stepper or something else? so that when the break is releasing it has somekind of holding torque bevor moving?

See reply #1. A PID controller can respond in milliseconds.
