Motor FAQs

What kind of brush is used in the motor?

We usually use two types of brushes: metal brushes and carbon brushes. The choice of brush depends on several factors, including the speed, current carrying capacity, and life expectancy of the motor. For smaller motors, we usually choose metal brushes; For larger motors, we tend to choose carbon brushes. Compared to metal brushes, carbon brushes have a longer service life and can significantly reduce the wear on the commutator.

What are the noise levels of your motors and do you have noiseless ones?

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.

What parameter information is needed for motor evaluation?

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.

Could you send me a quote/price list?

All of our motors are customized according to the specific needs of the customer, including life, noise level, voltage, shaft specifications, etc, and the price will vary according to the number of years, so it is difficult for us to provide a price list.

If you can tell us your detailed requirements and annual quantity, we will offer you a reasonable price for both parties.

Do you have products in stock? Can I have some samples?

All of our motors are custom made and are not in stock, so we may not be able to supply them if they are only needed for personal use or replacement. If it is to be used for sample testing before an official order, and you can accept our MOQ and price conditions, we are willing to provide samples.

How much is the sample cost?

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.

Does the motor have a detailed service life in Kinmore?

The service life of a motor will vary significantly depending on the model, material, and operating environment, including temperature, humidity, duty cycle, input power, and how the motor is coupled to the load. We usually need to ensure that the change of current, speed and torque of the motor in the running state is kept within the range of ±30% of the initial set value When we do the electrical life test.

If you can specify the specific requirements and working conditions, we will conduct a detailed assessment to determine which motor model best meets your needs.

Could you tell me the lead time for samples and orders?

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.

Can I visit the motor factory of Kinmore?

You are very welcome to visit us at any time, but please give us a few days' notice so that we can arrange the schedule and plan the visit.

Do you have any subsidiary or agent here?

We do not currently have any subsidiaries or agents, but we are open to future cooperation. We are always looking for partnerships with companies and individuals around the world who are willing to become our local agents, allowing us to serve our customers more closely and efficiently.

What is the minimum order quantity (MOQ) of the product?

The minimum order quantity (MOQ) of our conventional brushed DC motors and brushless DC motors is 5k-10k/Lot; and the minimum order quantity of conventional reduction motors is 1k/Lot.

What are the international shipping options and which countries/regions can you deliver to?

Our company has in-depth cooperation with international logistics, supporting express, sea, air and other transportation modes;

It can be delivered to all countries or regions in the world.

What kinds of certifications have the company's products passed?

Conventional products have passed RoHS and REACH certifications; EMC, CE, UL and other standards can be certified according to customer needs.

Can you provide other additional spare parts for the motor?

Yes, our company not only provides motor, but also provides leads, gears, worm gear, connectors, encoders and other spare parts customization.

What types of motors do you supply?

Kinmore mainly produces DC motors, including brushed DC motors, brushless DC motors, Gear motors, etc.

Can the motor be customized?

Yes, our R & D team can develop and customize the motor;

Motor customization projects include motor dimensions, internal structure, performance parameters and related custom accessories, etc, to meet the requirements of the motor working under different conditions.

What are the types of gears do you use in gearbox?

We now produce a complete range of gear types.

According to gear structure: straight teeth, helical gear, bevel gear, worm gear, worm gear;

Accroding to gear material: plastic teeth, metal teeth (copper, stainless steel, powder metallurgy).

Can I just order the gearbox without dc motors?

In order to ensure the quality and consistency of the product, we generally do not provide separate accessories/gearbox;

For customized gear motor needs, we will develop solutions according to the actual situation.

Can the gearbox be customized?

Yes, our R & D team can develop and customize the gearbox;

Gearbox customization projects include gear customization, dimensions, internal structure, performance parameters and related custom accessories to meet customer requirements.

Do you have any coreless/outer rotor brushless motors?

Our company has a complete range of brushless motors, and can provide motors with special structures such as coreless/outer rotor brushless motors.

What are the advantages of brushless motors?

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

You can refer to our brushless motor introduction page for details:
