YHD- H55 brushless DC motor 400W for vacuum cleaner

For all of our motors, they are customized based on different requirements. We will offer the quotation soon after you send your specific requests and annual quantity.

Normally, it takes 15-25 days to produce samples; about mass production, it will take 35-40 days for DC motor production and 45-60 days for gear motor production.

I am afraid not. The lifetime varies a lot for different Models, materials, and Operating conditions like temp., humidity, duty cycle, input power, and how the motor or gear motor is coupled to the load, etc. And the lifetime we normally mentioned is the time when the motor rotates without any stop and the Current, Speed, and Torque change is within +/-30% of the initial value. If you can specify the detailed requirements and working conditions, we’ll make our evaluation to see which one will be suitable to meet your needs.

we know, different shapes determine the size of the space, which means that different sizes can achieve performance such as different Torque values. Performance requirement includes working Voltage, rated load, and rated Speed, while the shape requirement includes the maximum size of the inStallation, out shaft size, and the direction of the terminal.
If the customer has other more detailed requirements, such as Current limit, working environment, service life requirements, EMC requirements, etc., we can also provide a more detailed and accurate evaluation together.
