The new original 1215 hollow cup model servo high-speed motor, the motor diameter is 12mm, which was originally used in the precision robot manipulator servo servo, the motor rating should be about 8V, and the high torque rare earth strong magnetic hollow cup motor.
The workmanship of the motor is very good. It is customized by a professional hollow cup manufacturer. The motor shaft comes with a 10-tooth gear with a module of 0.2. The inner shaft diameter of the motor is 1mm. The magnetic steel is rare-earth neodymium magnetism.
The measured speed of the 12mm hollow cup motor is as follows. It is estimated that the steering gear was originally used at 2S voltage. The test is for reference only:
Voltage 3V, no-load current 15mA, no-load speed 11000 rpm.
Voltage 5V, no-load current 18mA, no-load speed 19000 rpm.
The voltage is 8V, the no-load current is 26mA, and the no-load speed is 31000 rpm.
The motor with the motherboard weighs 6.8 grams.
