![56mm brushless gear motor 1]( "56mm brushless gear motor 1")
56mm BLDC Gear Motor for Medium-Load Motion Control
The 56mm brushless planetary gear motor is designed for applications where a compact motor needs to deliver stronger output torque after reduction. The brushless DC motor provides stable rotation and long service life, while the planetary gearbox converts motor speed into practical output torque for mechanical systems.
This makes the 56mm brushless planetary gear motor suitable for equipment that requires controlled movement, repeatable operation and stronger transmission capacity. It is especially useful in applications where smaller gear motors may not provide enough torque reserve or where brushed motors may not meet lifetime requirements.
24V Brushless Motor Platform with Hall Feedback
The representative 56mm brushless planetary gear motor model shown is based on a 24V DC brushless motor platform. The base motor provides rated torque of approximately 0.28N·m, rated current of approximately 3.39A, and rated speed of around 2000rpm before gearbox reduction.
The motor connection diagram shows Hall sensor and phase wiring, including Hall signal wires and motor phase wires. Hall feedback helps the controller detect rotor position, improve startup performance and provide more reliable operation during speed and direction control.
Wide Gear Ratio Range from 4.3:1 to 836:1
The gearbox ratio selection is one of the most important features of this motor series. The representative table includes ratios such as 4.3, 5.2, 6.75, 18, 29, 36, 79, 150, 236, 531 and 836.
Lower Ratios for Faster Output
Ratios such as 4.3:1, 5.2:1 and 6.75:1 are suitable for applications that require relatively faster output speed while still increasing torque. These versions can be used in rotating platforms, drive rollers, compact transmission modules and medium-speed automation systems.
Medium Ratios for Balanced Transmission
Ratios such as 18:1, 29:1, 36:1 and 79:1 are suitable for applications that require a balance of output speed, torque and gearbox length. These configurations are often used in actuators, robotic mechanisms, smart machines and automatic adjustment systems.
Higher Ratios for Low-Speed High-Torque Motion
Ratios such as 150:1, 236:1, 531:1 and 836:1 are suitable for low-speed, high-torque applications. These versions are useful for lifting mechanisms, locking modules, slow positioning systems, valve drives and heavy adjustment structures.
Planetary Gearbox Stages for Torque and Length Selection
The gearbox can be configured with 1-stage, 2-stage, 3-stage or 4-stage planetary reduction structures. The stage selection affects output torque, output speed, gearbox length and overall motor size.
A 1-stage gearbox is shorter and provides higher output speed. A 2-stage or 3-stage gearbox gives stronger reduction and higher torque. A 4-stage gearbox is suitable for very low-speed and high-torque requirements, but the total motor length becomes longer. This allows OEM engineers to balance torque requirement, available space and mechanical design.
Engineering Selection Notes
Define the Final Output Speed First
For a brushless planetary gear motor, the final output speed is determined by the motor speed and gearbox ratio. Before selecting a model, customers should confirm the required output rpm at the shaft.
If the application requires faster movement, a lower gear ratio may be suitable. If the application needs slow and controlled movement, a higher gear ratio should be considered.
Confirm Working Torque and Peak Load
The required torque should include normal running torque, starting torque and peak load. For applications with frequent start-stop, reversing, lifting or sudden load changes, torque margin is very important.
The representative data shows output torque options from approximately 1.1N·m to 153.6N·m depending on ratio. Customers should not select only by maximum torque. The correct choice should also consider gearbox strength, duty cycle, lifetime and installation condition.
Match the Motor with the Correct BLDC Controller
56mm brushless planetary gear motor requires a suitable BLDC controller. The controller should match the motor voltage, current, Hall sensor signals and motor phase wiring.
Customers should confirm whether the system requires speed control, direction control, PWM input, analog speed control, braking function, alarm output or communication interface. Correct controller matching helps improve startup stability and motion performance.
Consider Gearbox Backlash for Positioning Systems
For positioning applications, gearbox backlash can affect repeatability and control accuracy. If the motor is used in robotic joints, precision tables, valve positioning or adjustment systems, customers should discuss backlash requirements during the sample stage.
Evaluate Heat Rise Under Real Working Conditions
Even though brushless motors have good efficiency and long life, heat rise still depends on load torque, current, working time, gearbox ratio, ambient temperature and installation environment. For continuous operation or high-load intermittent operation, real-load testing is recommended.
