Why can something as simple as copper wire winding determine the fate of an industrial motor worth tens of thousands of yuan? In the three-phase induction stator winding process, those precisely arranged enameled wires hide deep electromagnetic secrets. This article reveals the complete process—from the pretreatment of three-phase stator and rotor cores to final varnishing and curing.
This article delves into the variances between inner rotor and outer rotor permanent magnet motors, shedding light on their distinctions and practical implications.
Soft magnetic materials play a crucial role in motor lamination stacks. These materials are defined by their ability to be magnetized with a coercivity (Hc) of less than 1000A/m. This blog will explore various soft magnetic materials and their characteristics, focusing on their use in motor laminations.
Silicon steel (electrical steel) refers to a very low carbon ferrosilicon alloy with a silicon content of 0.5% to 6.5%. Due to differing structures and applications, they categorize silicon steel into non-oriented and oriented types. B50A470 cold-rolled electrical steel is widely used in the manufacture of motor cores. In this article, we will focus on the properties of B50A470 non-oriented silicon steel.
Coreless motors offer numerous advantages, but selecting the best one requires careful consideration. These motors are known for their efficiency, lightweight design, and quick response.
Why is it the ideal choice of frameless torque motor for humanoid robots? Unlike traditional motors, frameless torque motors are compact and lightweight, offering greater design flexibility and higher torque density. They are specifically tailored to meet the demands of humanoid robot joints, providing rapid response, low friction, and high efficiency.
As the automotive industry continues its transition towards sustainable energy solutions, the development of electric vehicles (EVs) has become a focal point. In this blog post, we delve into the advancements in high-performance iron core materials for new energy vehicle motors, exploring five key technological routes driving innovation in the era of high power density.
How are motor laminations made? Key technical requirements for motor lamination include material selection, manufacturing methods, and various technical processes such as pressing and bonding.
Motor core lamination stacking is a crucial step in the manufacturing of electric motors and generators. It involves the assembly of thin, insulated steel sheets, called laminations, to create the core of the motor. In this comprehensive guide, we’ll explore several methods of motor core lamination stacking commonly used in the industry to generate the electromagnetic field essential for the motor’s operation.
Have you ever wondered how the small axial flux stator cores are made? There are two mainstream approaches: One is using silicon steel sheets, which are stamped and then wound into shape, much like a “coreless roll of paper.” The other method uses SMC (Soft Magnetic Composite) powder injection molding.
