Product Description
Coreless motor structure features
Designed for industrial power tools, this DC motor is 22mm in diameter and 38mm in length and has a coreless construction. The coreless design means that the rotor has no iron core, and its unique winding method results in a lightweight and flexible rotor construction. The rotor inertia under this structure is very small, like a smart spirit, with fast starting and braking capabilities. In industrial production, this fast response characteristic can greatly improve work efficiency, so that power tools can be quickly put into or stop working to meet the needs of frequent operations.

Technological Innovation
Low heating characteristic
The low heating characteristics of coreless DC motors are also a major advantage in industrial environments. Due to the reduced energy loss, the motor generates relatively little heat during operation. The lower calorific value not only helps to extend the service life of the internal parts of the motor, but also avoids safety hazards caused by overheating. In closed or high-temperature industrial working environments, this low heating characteristic enables continuous and stable operation of the motor, ensuring the safety and reliability of industrial power tools.

Efficient operation
One of the core advantages of this 12V coreless DC motor is its efficient energy conversion capability. The coreless structure eliminates the hysteresis loss and eddy current loss caused by the iron core, just like opening up an unobstructed highway for the energy transmission of the motor. In industrial applications, this means that the motor can convert more electrical energy into mechanical energy, reducing energy waste and reducing production costs. Whether it is continuous operation for a long time or frequent start-stop working mode, the motor can maintain efficient operation, providing stable and strong power for industrial power tools.
Compact size with rugged housing
The compact size of the motor makes it a perfect fit in the limited space of industrial power tools. With a diameter of 22mm and a length of 38mm, it can be easily integrated into a variety of handheld or small industrial electric devices. At the same time, the motor housing is made of high-strength materials, providing a reliable protective barrier for the precision components inside. This shell is like a strong armor, which can resist the invasion of dust, debris, moisture and other adverse factors in the industrial environment, ensuring that the motor is still stable operation under harsh working conditions.
Size & Interface
Quality Control
Assembly link control: tight seam
The assembly process of the motor is like a precise jigsaw puzzle, where every component must be fitted into place without error. Our assembly workers are professionally trained, have rich experience and a high sense of responsibility. When assembling the hollow cup rotor, ensure that its position in the stator is accurate and the clearance with the brush and commutator is just right. The tightening torque of each screw is precisely calculated and strictly controlled to prevent the overall performance of the motor from being too tight or too loose. After the assembly is completed, the appearance of the motor is also carefully checked to ensure that no parts are loose, scratched or improperly assembled.
Performance testing: Comprehensive inspection
We have a set of perfect performance testing system, for each hollow cup brush motor for comprehensive and strict inspection. In terms of electrical performance detection, the starting current, no-load current, rated power, speed and torque of the motor are measured by high-precision test equipment to ensure that these parameters are within the specified tolerance range and meet the design requirements. For the mechanical properties of the motor, we simulate the actual working environment and carry out long-term operating tests to observe the vibration, noise level and heating degree of the motor. Only motors that are fully qualified in all performance indicators will be labeled as qualified in quality and enter the market.
Durability test
In order to ensure the reliability and life of the motor, we will carry out a long time durability test on the motor. In the simulation of various actual working conditions, the motor is continuously run for hundreds of hours, during which the performance indicators of the motor are continuously monitored, such as temperature changes, vibration conditions, electrical parameter stability, etc. Only motors that pass the durability test and have no significant degradation in performance will be considered qualified products.
Quality traceability system: Tracing to the source
In order to ensure the continuous stability of quality, we have established a sound quality traceability system. Each hollow cup brush motor has a unique identity, from the procurement batch of raw materials, all aspects of the production process data to the final test report, are recorded in detail. Once a quality problem is found, it can be quickly traced back to the root of the problem, and effective corrective measures can be taken to avoid the recurrence of similar problems.
Application Cases
Drilling class power tools
In the hand-held drill, bench drill and other drilling tools, the high torque and speed regulation performance of this motor can meet the needs of different materials (such as wood, metal, plastic, etc.) drilling. Its efficient operation and reliability ensure the stability and efficiency of the drilling process, so that the drilling tool can continue to work for a long time without performance degradation.
Grinding and polishing power tools
For grinding and polishing tools such as Angle grinders and polishing machines, the speed regulation performance and low heating characteristics of the motor play an important role. The operator can precisely adjust the speed according to the material and process requirements of the grinding or polishing to achieve a fine surface treatment. At the same time, the low heating characteristic avoids the damage to the motor and tools caused by high temperature caused by long-term grinding, and improves the service life of the tools.
Cutting power tools
In cutting tools such as hand-held chainsaws and cutting saws, the high power density and fast response ability of the motor can provide enough power for the cutting blade. Whether cutting wood, metal pipes or other materials, the motor ensures that the cutting tool starts up quickly and runs stably, enabling efficient and precise cutting operations.
