High-efficiency coreless three-phase brushless motor with rare-earth permanent magnets designed for applications that require strong torque, low loss, and reliable starting performance. Key benefits - High torque with low loss due to dual-rotor rare-earth magnets and ironless (coreless) design, providing efficient power delivery for demanding loads. - Easy to start and smooth operation because of the inner-rotor configuration and balanced double-rotor construction, enabling reliable low-speed response. - Durable construction with a metal rotor shell and baked protective coating combined with a stainless steel output shaft for extended mechanical life. - Encapsulated stator for improved resistance to dust and moisture because the stator is cast in white epoxy resin for reliable insulation and protection. - Lightweight and compact form factor that delivers 100 W rated power while keeping overall mass around 455 g for applications where weight matters. Key specifications - Rated power: 100 W. - Rated voltage: 1 to 36 V DC. - Rated current: 0.05 to 8 A. - Speed range: 100 to 410 rpm. - Motor diameter: 90 mm. - Motor thickness: approximately 28 to 30 mm. - Motor overall size: approximately 90 x 30 mm. - Shaft size: 8 mm diameter by 30 mm length, made of stainless steel. - Magnetic pole configuration: 12 pairs of magnetic poles. - Magnet pole thickness: 5 mm. - Motor weight: approximately 455 g. - Output: three-wire three-phase output, requiring a three-phase brushless DC driver for operation. Materials and construction - Rotor shell: metal construction with baked protective coating to resist corrosion and mechanical wear. - Shaft: stainless steel for strength and durability. - Stator: encapsulated in white epoxy resin to provide dustproof and waterproof protection and rigid insulation. - Magnet system: dual-rotor rare-earth strong magnets to increase torque density and reduce magnetic losses. Compatibility and drive requirements - This motor provides a three-wire three-phase output and requires a compatible three-phase brushless DC driver capable of handling the specified voltage and current ranges. - Suitable for applications that can accept an outer diameter of 90 mm and a shaft diameter of 8 mm with 30 mm shaft length. Practical applications - Laboratory and research setups where compact, high-efficiency brushless motors are needed for experiments and prototype development. - Electromechanical and magnetic motor research, including magnetic drive and experimental motor designs that require dual-rotor rare-earth magnet configurations. - Precision hobby or custom equipment that needs high torque at low speeds and reliable starting performance, such as small rotary drives and actuation systems.
