Straight strip winding iron core(

Brushless stator 87-12-5.2-H7.5 straight


The straight motor core is an important component in the motor. It is mainly used to concentrate magnetic conduction and improve the efficiency and performance of the motor. The motor core is generally made of silicon steel sheets or other magnetic materials, which have good magnetic permeability and low loss characteristics. The shape of the motor core is generally a straight strip to effectively concentrate magnetic conduction inside the motor and enable the motor to generate a strong magnetic field.

The design and material selection of the motor core have an important impact on the performance and efficiency of the motor. A high-quality motor core can reduce energy loss, improve the efficiency and reliability of the motor, and at the same time reduce the operating noise and vibration of the motor. Therefore, in motor design, it is crucial to select the appropriate core material and structure.

Motor Stator injection molding(

New energy / automotive motor cores, Yuma Precision currently has rich project experience in the development of automotive motor cores. At the same time, we have cooperated in the development of new energy pure electric/hybrid vehicle drive motors, compressor cores, and automotive power steering motors, automobile oil pump motor core, window motor core and other dozens of automotive products. It has rich experience in cooperation and development, and combines iron cores with rubber-coated parts to optimize the product structure.

)

Motor Stator injection molding(

Generally speaking, the role of core injection molding is to comprehensively protect, insulate and improve the overall performance of the motor, making it more suitable for operation in different environments and working conditions. This process is usually used for core protection in motors, transformers and other equipment to ensure long-term stable operation of the equipment.

Stepper Motor Core(

From the perspective the difficulty of stamping process of stator and rotor core, the production scheme of the stepper motor iron core stamping is undoubtedly one of the series with the highest comprehensive difficulty in the stamping industry. Under the condition that the stamping production of stator and rotor is carried out through zero clearance, the product can achieve rotary lamination at the same time, and finally achieve the micro interference state of stator and rotor, which not only reduces the cost but also meets the needs of customers for the amount of motor wear; And the product after rotation from the form and position tolerance, motor performance has been improved significantly. Yuma Precision continues to advance the development of stepper series. At present, it has 9 series, 33 models and more than 10,000 pieces of materials, providing sufficient model selection for stepper motor standard parts market.

)

servo motor core(tooth yoke separation)(

The stator adopts the combined structure of tooth and yoke, which greatly reduces the production cost of iron core compared with the conventional segment structure. In the design of the rotor, the magnetic steel structure adopts IPM structure. Compared with the conventional SPM structure, the cost of the magnetic steel is reduced synchronously. Moreover, the stator and rotor punched from one die, and the cost of a set of iron core is reduced by more than 15% compared with the previous scheme.

Linear motor core(

Length: 181.72mm

Height: 50mm

Pole number: 6


The linear motor core is usually composed of silicon steel sheets. The main function of silicon steel sheets is to reduce magnet losses and eddy current losses. Silicon steel sheets have good magnetic permeability and low magnetic permeability, which can effectively conduct magnetism and reduce energy loss in linear motors. Silicon steel sheets are usually stacked, bonded, and processed to ensure the efficient operation of linear motors. Parameters such as the thickness and magnetic permeability of the silicon steel sheet are selected according to the design requirements of the linear motor to ensure the performance and efficiency of the motor.

Linear motor cores are widely used in electronic and semiconductor equipment, photovoltaic lithium battery industry, UV inkjet printing industry, precision CNC machine tools, high-end medical equipment, mobile phone testing industry, glass testing industry and other fields.
