Banding radial magnetic ring, encoder has been assembled with copper columns and screwsMotor with 3P MX1.25 line, encoder with 4P pH2.0 rotor DuP line. Support FOC control, you can use the SimpleFoc library, DENGFOC library, support 0Drive (voltage control 12V), and also support the opening control. The tin iron boron is strong magnetic, the outer rotor, the mid -empty shaft φ6.5mm, the maqnetic rinq φ5.4, can be across the line Can be used to learn DC brushless motor control, such as FOC, SVPWM, square wave It can make preferential motors such as small robots, self -balanced cars, gimbal, drones, wheel -toot robots, KNOD smart knobs, lidar, etc. The motor is a copper -core stator, shell aluminum alloy, black paint, rotating wireless toothless setting, high and low speed (FOC control self-test)Coder supports I2C, PWM/Simulation Communication Color: Black Material: Metal+Plastic Package Contents: 1 x DC motor;1 x magnetic encoder;1x SimpleFOCmini driver board 1TF Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
