Product Description

Stock brand new high-power 5820 external rotor brushless motor, built-in brushless drive, rare earth medium-strong magnetic high-torque external rotor, motor supports forward and reverse switching, self-stop, PWM 5V signal stepless speed regulation, with speed pulse square wave signal feedback output , The overall workmanship of the motor is very good. The bearing adopts Japanese NMB silent ball bearings, 12 large-torque stator coils, and a rare earth strong magnetic outer rotor.

The original package of this motor is nominally 5820, and the actual measured rotor thickness is 17, and it may be called 5817 in some places, but these are not important. The actual specifications of the motor are still required, and there are detailed instructions on the page.

The nominal voltage of the motor is 24V, and the power of similar products on the Internet is about 100W. In this type of external rotor motor, the power is very large, the small size and high power motor, and the 12-pole stator torque will also be very good. The measured voltage of the motor can run normally between 5-24V. If you only need the highest speed to run and power on, you only need to connect the positive and negative poles of the power supply. Low voltage, low motor speed, low power, high voltage, high motor speed, high power, rotor torque is very strong in high-speed operation, much more powerful than conventional nidec fan outer rotor brushless motors.

The measured speeds of the motors at different voltages are as follows, for reference only. If the PWM signal is used to adjust the speed, it can run at a lower speed. The PWM signal board can be purchased separately.

The voltage is 5V, the no-load current is 0.14A, and the maximum no-load speed is 710 rpm.

The voltage is 12V, the no-load current is 0.2A, and the maximum no-load speed is 1850 rpm.

The voltage is 24V, the no-load current is 0.28A, and the maximum no-load speed is 3800 rpm.

The no-load current can be directly compared here, and the power is not small. Priced for a single motor, the motor weighs 220 grams.
