Hollow cup motors are a special type of motor. The main feature is that the rotor part of the motor adopts a hollow cup shape design. This design gives the hollow cup motor a series of unique characteristics. The following is the summary of the main characteristics of hollow cup motors by X-TEAM brushless motors:
- Compact structure and lightweight
Small volume: The rotor of the hollow cup motor adopts a hollow cup shape, which makes the volume of the entire motor relatively small.
Light weight: Due to the optimization of the rotor structure, the weight of the hollow cup motor is also greatly reduced, which is convenient for installation and carrying.
- High speed and high efficiency
High speed: The rotor of the hollow cup motor is light and has a small moment of inertia, so it can reach a higher speed in a short time, which is suitable for application scenarios that require high-speed rotation.
High efficiency: The air gap between the rotor and the stator is small, the magnetic circuit loss is small, and the energy conversion efficiency is high. The maximum efficiency of some products can reach more than 90%, which is much higher than that of traditional iron core motors.
- Low noise and stability
Low noise: The rotor design of the hollow cup motor reduces air resistance and reduces noise during operation. At the same time, the low vibration brought by high speed also further reduces the noise level.
Stable operation: The speed fluctuation of the hollow cup motor is very small. As a micro motor, its speed fluctuation can be controlled within 2%, ensuring the stability of operation.
- High reliability and long life
High reliability: There is no contact between the rotor and stator of the hollow cup motor, and there is no wear problem, so it has high reliability.
Long life: Due to its compact structure, light weight, small moment of inertia and low wear, the service life of the hollow cup motor is relatively long.
- Good control performance
Precise control: The hollow cup motor can achieve precise speed and position control through PWM control, which is suitable for application scenarios requiring high-precision control.
Fast response: The hollow cup motor starts and brakes quickly, responds very quickly, and the mechanical time constant is less than 28 milliseconds. Some products can reach less than 10 milliseconds.
- Wide range of application fields
Medical equipment: such as ventilators, infusion pumps, surgical robots, etc., require high-precision, high-speed and low-noise motors.
Aerospace: such as satellite attitude control, UAV power system, etc., require motors with high reliability and strong adaptability.
Industrial automation: such as robots, automated production lines, precision positioning systems, etc., require motors with high efficiency, stability, and controllability.
Household appliances: such as fans, vacuum cleaners, electric toothbrushes, etc., require motors to be energy-saving and low-noise.
Automotive industry: such as electric windows, seat adjustments, wipers, etc., require motors with small size, light weight, and high efficiency.
Precision instruments: such as optical instruments, measuring instruments, etc., require motors with high reliability and high precision.
Coreless motors, with their unique structural design and excellent performance characteristics, have shown broad application prospects and huge market potential in many fields. With the continuous advancement of technology and the continuous development of the market, coreless motors will play an important role in more fields.
