Driven by modern technology and precision manufacturing, permanent magnet motors have become essential components across industries. Their compact size, energy efficiency, and powerful performance make them a widely available and critical solution in today's automation, robotics, and smart equipment.
Unlock the full potential of your designs with high-performance permanent magnet electric motors.
Permanent magnet motors (PM motors), or permanent magnet electric motors, are a class of motors that utilize permanent magnets embedded in or attached to the rotor to create a constant magnetic field. Unlike traditional motors that rely on field windings and external excitation, PM motors operate more efficiently with fewer components and greater reliability.
The roots of PM motors trace back to the early 20th century when basic magnetic materials like cobalt steel were used in early motor designs. With the introduction of ceramic magnets in the 1950s and the revolutionary development of rare-earth materials like neodymium (NdFeB) in the 1980s, PM motors evolved into a powerful force behind countless modern technologies. PMDC motors (Permanent Magnet DC Motors), a specific type of DC motor permanent motor, have become widespread in portable devices, robotics, and compact drives. Today, companies like BG Motor are leading this evolution, providing advanced solutions built on three decades of R&D.
Permanent magnet motors generate torque by using a static magnetic field from permanent magnets in combination with electrical currents in the stator windings. When electric current flows through the stator, it creates a rotating magnetic field that interacts with the rotor’s magnetic field, causing rotation.
Unlike conventional motors, PM motors require no excitation current, making them more efficient and thermally stable. At BG Motor, our motors leverage advanced electromagnetic simulation (ANSYS, Motor-CAD) and precision production methods to achieve outstanding energy efficiency and compact form factors. Our permanent magnet electric motors offer long life cycles, low maintenance, and ultra-low noise—making them ideal for demanding applications across industries.
Permanent magnet motors fall into several key categories, each suited for specific uses:
PMDC Motors (Permanent Magnet DC Motors): Compact, cost-effective motors used in small appliances, toys, and medical devices. Simple design, runs on DC voltage.
Permanent Magnet Synchronous Motors (PMSM): High-efficiency AC motors ideal for industrial drives, EVs, and robotics. Precise control with field-oriented algorithms.
Permanent Magnet Stepper Motors: Used in precision motion systems like 3D printers, CNC machines, and camera controls.
Each type of PM motor shares common advantages: excellent power-to-size ratio, high starting torque, and stable operation. BG Motor provides all major types of permanent magnet electric motors with customizable features to meet your exact performance needs.
Permanent magnet motors are deeply integrated into the equipment driving today’s smart world. BG Motor supports a wide range of applications, including:
