Nema 17 Stepper Motor Heat Sink

Heat sink for a nema 17 stepper motor used on most desktop 3d printers and in many other applications.

Nema 17 stepper motor heat sink.

At 1 4 amps instead of 2 amps by suitably adjusting the current limit on the a4988 or else. Thermal tape is required to attach the heat sink onto the the face s of the motor. All 3d printers utilize stepper motors to create the motion needed to manufacture 3d prints and most of those stepper motors are the nema 17 form factor. We stopped using the shields and built the circuit with a4988 driver with a 1 2a 12v nema 17 stepper motor.

These heatsink was designed by us to help cool the stepper motor near the extruder hot end of your 3d printer. Nema 17 stepper damper stepper motor vibration dampers heat sink for. 60 or 80c rise above ambient isn t unusual you are expected to bolt the motor to something metal to take the heat away. Stepper dampers are used to decrease noise and resonance in your cnc and 3d printer eliminating vibration and effectively improving 3d printing quality.

Also stepper motors get hot that s what limits the drive current. Also for use on any nema17 motor that is in an area with restricted airflow is on for extended periods of time or that is mounted close to a source of heat.

This heat sink is mounted on the back of a nema 17 stepper motor to reduce the heat in the motor.

Tcpoly s composite fdm filament allows for printing heat sinks and other electronics cooling devices. Bntechgo black aluminum heat sink cooling fin 4 pcs 40mm x 40mm x 11mm silicone based thermal pad 4 pcs 40mm x 40mm x 0 5mm. The heat sink is the same form factor of a nema 17 stepper motor and has holes lighing up with the motor holes. Using this device we saw a 25 reduction in temperature increase on our lulzbot taz 5 s steppers.

You have a motor where ir is 12v so you ll need a minimum of 24v preferably 36v to get any sort of performance from a chopper driver. These heat sinks have an adhesive back that allows them to be directly attached to the back of a stepper motor. Either run the motor well below its rated current i e. Material black anodized aluminium.

It s common for stepper motors especially with prolonged usage to generate excess heat. A a4988 will struggle to supply 2 amps even with a large heat sink and a cooling fan.
