Featuring a 42×42mm end cap size, compact body length ranging from 53mm to 93mm, and standard 24V DC voltage input, this motor delivers stable power output from 32W to 95W, rated torque of 0.1N.M to 0.3N.M, and a standard rated speed of 3000rpm (max speed up to 5000rpm). With high-quality sintered NdFeB magnets and precision winding technology, it is the ideal drive core for precision machinery manufacturers and automation solution providers needing compact, high-accuracy motion control.
The 42mm sintering brushless DC motor adopts an industry-leading sintering process, which optimizes the magnetic circuit structure and material density, delivering superior motor performance compared to conventional miniature BLDC motors. It achieves an operating efficiency of over 90%, delivering 20% to 30% more energy savings than traditional brushed motors, reducing power consumption for battery-powered and low-power equipment.
With a 42×42mm frame size and ultra-compact body, this miniature brushless DC motor saves valuable installation space, making it perfectly suited for equipment with extremely limited internal layout. Its lightweight design (0.35kg to 0.75kg) also reduces the overall weight of the end equipment, meeting the lightweight design needs of precision instruments and robotic applications.
Equipped with a high-precision encoder and supporting PID closed-loop control, this 24V precision brushless DC motor achieves speed fluctuations of less than ±1%, ensuring ultra-stable torque output and fast response for precision motion control. Optimized electromagnetic design and dynamic balancing guarantee operating noise below 50dB, enabling smooth, quiet operation in noise-sensitive precision scenarios.
This miniature sintered BLDC motor is widely used in precision industrial and commercial scenarios requiring compact size and high accuracy, including collaborative robots, precision valve control, medical precision equipment, 3D printing equipment, optical instruments, intelligent access control systems, small automation actuators, and various precision machinery and power devices.
We offer comprehensive customization services for precision equipment manufacturers and automation solution providers to meet diverse application needs. Customizable items include motor shaft dimensions, mounting hole positions, lead wire length, sintering process adjustments, as well as matching gearboxes, high-precision encoders, brakes, and controllers to achieve customized speed, torque, and control performance.
