Motor stator and rotor iron core is a common anti-interference component in electronic circuits, which can well reduce high-frequency noise. It is usually made of ferrite materials, which is commonly used in automobiles, electronic products and electric tools. Motor iron core is also a very important accessory, which can not only generate rotating magnetic field, but also start the effect of protecting the stator in the motor, so as to reduce the possibility of motor damage.

As a company focusing on the R & D and manufacturing of stator and rotor cores of small and medium-sized motors, Yuma precision technology (Jiangsu) Co., Ltd. (hereinafter referred to as Yuma precision) is a professional manufacturer of stepping motor cores, servo motor cores, new energy stator and rotor cores and brushless motor cores.

Introduction to some products

Product introduction

Yuma precision series stepping stator and rotor iron core

The stepping motor iron core adopts large rotation lamination, which offsets the problem of the same plate difference in materials, so that the parallelism, flatness, end face runout, rotor dynamic balance and other parameters of the product can achieve the ideal effect of customers. At present, it is widely used in 35 million sets of stage automation and office automation equipment.

In terms of new product research and development, Yuma precision will continuously optimize the product tooth shape / groove shape / inner hole according to the needs of customers, so as to obtain higher quality new products. At the same time, through the optimization of products, continuously improve the cost performance of products.

Yuma precision series servo stator and rotor iron core

Yuma precision servo series are block products, with a series of standard iron cores, covering the whole series of 40 / 60 / 80 / 90 / 100 / 110 / 130 / 180 / 220 / 250.

It has only been 5 years since entering the servo industry, from the initial V-shaped riveting point process to the round riveting point process, and then to the straight wall riveting point. At the same time, it has been upgraded from the product structure to the chute structure; Every attempt has greatly improved the product accuracy from different aspects.

Over the past five years, Yuma precision has always adhered to the perspective of customer use and formulated a series of internal standards through the collection of mass production data, so as to better ensure the quality of products.

Yuma precision brushless series products

Yuma precision brushless series products are gradually being introduced to the market. At present, there are three products of 42 series / 57 series;

In the future, Yuma precision will improve its series products into 42 series / 57 series / 60 series / 80 Series / 86 series / 110 series / 130 series, etc.
