Used disassembled ultra-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,

The estimated speed of full power is about 10W, ultra-high-speed motor,

Such a high speed requires extremely high motor balance,

Therefore, the rotor and impeller of the motor are both dynamically balanced.

The bearings are all imported ball bearings.

This motor can run when it is energized,

But the operating power is estimated to be only in the low-speed gear,

The current is about 5A at 25V,

The measured speed is more than 50,000 revolutions,

I don’t know how to switch to the high-speed and high-power gear at the moment.

At that time, I will update the introduction if I see the feedback from netizens.

One of the sockets on the side of the motor motherboard is 2 small sockets,

Another one with a small socket,

Random shipments

There is no parameter label sticker on the part of the casing of the fan disassembled.

Motor rated voltage 25.2V, power 350W,

It should have been powered by a 7S lithium battery,

The measured limit voltage can be used between 20V-30V,

Yellow positive pole and blue negative pole of the motor,

Or red positive and black negative,

Be sure to confirm the positive and negative poles before wiring,

Wrong connection will burn the drive circuit.

The fan must not directly suck foreign objects or liquids such as water into the impeller.

Otherwise, the motor will be damaged.

The motor is a high-power brushless motor,

So the power supply must have a large current,

The minimum power supply needs to be about 20A or more,

Lithium batteries need high-current power cells.

The motor is suitable for retrofitting portable vacuum cleaners,

Or large-flow disinfection spraying machine and so on.

The motor weighs approximately 230 grams.
