KY-040 Rotary encoder

Other Hardware Sensors
1

Hello,
I want to ask about the rotary encoder sensor ky-040, as we know that sensor have a D-shape shaft to rotate it manually.

Can i attach that shaft to a motor dc back shaft?
I had try to connect that shaft using a coupler. But when i start rotating the motor dc, the encoder shaft turn as well but the encoder became hot. It is because the friction?

Anyone know how fast can i turn that ky-040 rotary encoder sensor?
Any idea to attach a motor dc with a rotary encoder?

Thank you.

Those encoders are made to be turned by human hand. They have plain unlubricated bearings and mechanical switches. Totally unsuited for connection to a motor.

Attaching an encoder to a motor can be challenging and expensive. My suggestion is to find a motor that suits your needs that has a built in encoder. A Google search for "dc motor with encoder" might turn up what you want.
