Second gear High-power three-phase brushless motor 21.6V150W ultra high speed constant power vacuum cleaner blower |

Used disassembled machine with shell super high-speed three-phase brushless vacuum cleaner motor. This motor was originally used on high-end rechargeable vacuum cleaners. The motor has a built-in high-power brushless drive, and the maximum no-load current at full power is about 7.5A. The speed is very high. The high speed of the tidal high-speed motor has extremely high requirements on the balance of the motor, so the rotor and impeller of the motor have been dynamically balanced, and the bearings are all imported ball bearings. In addition, the air duct of this fan is slightly different from that of common dust suction fans. This fan is an independent air duct, and the air intake will not pass through the inside of the motor. There is a fixed spiral decompression air duct on the outside and a circuit board at the tail. There is a cover and a rubber ring inside is sealed.

The motor has a nominal rated voltage of 21.6V. It was originally used with 6S (6 strings) power lithium battery packs. The actual test limit of 16-25V can be used. Moreover, the regulated voltage fan under a fixed gear is basically a constant power. Decreasing the voltage and current will increase to stabilize the power. Rated 21.6V test high-speed gear current up to 7.5A, low-speed gear no-load current 2.3A.

There are 5 outgoing wires of the motor, and the control operation is very simple, no additional input signal and other operations are required. The definition page of the wires has pictures and instructions. Simple use After directly powering on, the blue signal line will short-touch the positive pole of the power supply to turn on, and the short-touch negative pole will shut down. The green line is the gear signal line. Please see the picture for the specific wiring, please make sure that the positive and negative poles are not connected wrongly, otherwise the drive circuit will be burnt.

The fan should not directly suck foreign matter or liquid into the impeller. Although this motor has a sealing cover, there is still a very high probability that the fan may be damaged.

The motor is a high-power brushless motor, so the power supply must have a large current. The lithium battery needs a high-current power cell. The motor is suitable for retrofitting a portable vacuum cleaner, or a large-flow disinfection atomizing sprayer, etc.

These fans are delivered in bulk, so there will be bumps and frictions on the appearance. Most fans have a soft plastic protective cover for the air inlet. The tail wire, especially the signal wire, may be pulled and opened. The inlet of the fan There are two kinds of spray paint black and metal primary colors, the appearance is somewhat oxidized, the fan nut will have slight rust, etc., the overall color is good, if you mind, please don't buy it, thank you! Delivery test.

The motor with a housing weighs approximately 290 grams.
