FF-030A

Our motor noise control is at the leading level in the industry;

Usually, we define the noise level of the motor (in dB) based on the background noise and the measurement distance.

Noise is divided into two categories: mechanical noise and electrical noise. Mechanical noise is mainly related to the structure of the motor itself and the running speed of the motor (generally speaking, the faster the speed, the greater the noise), while electrical noise mainly comes from the sparks generated by the friction between the brush and the commutator.

Currently, there is no noiseless motor in the motor industry. We will improve the design to make the noise of the motor reach the level required by customers.

For low-cost samples less than 5 pieces, we can provide them free of charge, but the freight should be borne by the customer (the customer can choose to provide the tracking number or arrange the Courier to pick up the package, both of which are acceptable to us); For samples in excess of this quantity, or customized products, we will charge the corresponding sample fee and shipping.

Compared with the brushed motor, the brushless motor has the advantages of high efficiency, long life, low noise, and various control methods.

Customers need to clearly provide the performance and shape requirements of the product (different shapes determine the size of the space, which will be directly related to the performance that different specifications can achieve such as torque values are different). Performance requirements include operating voltage, rated load, rated speed and other parameters, and appearance requirements include the maximum installation size, shaft size, terminal direction and so on.

In addition, if the customer has other more detailed requirements such as current limits, working environment, service life and EMC standards can also be provided together, which will help us to carry out a more accurate and comprehensive assessment to ensure that the final product can meet the customer’s individual needs.

The delivery time of general DC motor samples is usually 10 to 15 days, and the delivery time of gear motor samples is 15 to 20 days.

If there are special customized requirements, such as lengthening the shaft, special reduction ratio, etc, the delivery time will be extended accordingly.

The standard order lead time is 35 days, but this time can be adjusted according to different models, production cycles and order quantities.
