I've been thinking about "experimenting" with dynamic braking on a little Schwinn scooter. I know it is not practical, I just wanted to try it for fun and to learn something new.
My scooter with batteries and rider weighs less than 275 pounds. I don't go over 20 mph. I can already lock-up the rear wheel with the disk brake at full speed, so, once again, I certainly don't NEED dynamic braking. I have a 36V 750W Permanent-Magnet Brushed Stock Currie motor. I overvolt the motor to 48V from a YI-Yun LB37 Controller.
I was thinking about using a 6-terminal solenoid, and a brake lever with a switch, to disconnect the negative between the controller and motor; and connect the negative motor lead directly to the positive motor lead to quickly slow down.
My question is: Do I need to use a resistor, or will it not matter at all in my case? If I was to use one to regulate the rate of braking, how would I know what resistor to get? Specs? Is there any risk of harm to any components if I do NOT use a resistor?
I appreciate any and all comments. Thanks.
