Product Description
Unique hollow cup structure
This hollow cup DC motor features an innovative hollow cup rotor design. Unlike traditional motor rotors, hollow cup rotors are made of wire woven into a cup-like structure without an iron core. This unique structure enables the motor to have a range of excellent properties.
Because there is no iron core, the motor avoids the hysteresis and eddy current losses generated by the iron core, which greatly improves the efficiency of the motor. At the same time, the moment of inertia of the hollow cup rotor is very small, so that the motor can start and stop quickly, and has an excellent response speed, which can meet the application scenarios with high dynamic performance requirements.

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.
