44mm brushless planetary gear motor – Product Overview
![44mm brushless gear motor]( "44mm brushless gear motor")
44mm BLDC Planetary Gear Motor for Controlled Motion Systems
The 44mm brushless planetary gear motor is designed for equipment that needs compact installation, controlled rotation and higher torque output after reduction. The brushless motor provides high-speed input, while the planetary gearbox reduces speed and increases output torque. This structure is suitable for applications where direct motor output is too fast or does not provide enough torque.
Compared with brushed gear motors, 44mm brushless planetary gear motor has no brush wear, lower maintenance demand and better suitability for frequent start-stop operation. It is a strong option for OEM customers who need a reliable motor solution for long-term operation, speed regulation and compact mechanical transmission.
24V IPM Brushless Motor Platform
44mm brushless planetary gear motor uses a 24V brushless DC motor platform. The representative motor data shows a no-load speed of approximately 9411rpm and rated speed of approximately 8000rpm before gearbox reduction. After the planetary gearbox is added, the final output speed and torque can be selected according to the gear ratio.
The product name shown in the parameter table includes X44IPM035, which indicates an IPM-style brushless motor configuration. This design is suitable for applications requiring stable output, compact motor structure and efficient power conversion.
Wide Gear Ratio Range for Flexible Output Selection
The gearbox ratio range is one of the most important advantages of 44mm brushless planetary gear motor series. The representative table includes ratios such as 3.5, 4, 6, 16, 24, 36, 64, 144, 256, 576 and 864.
Low Ratios for Faster Output Speed
Ratios such as 3.5:1, 4:1 and 6:1 are suitable for applications that need relatively high output speed while still improving torque. These configurations can be used in fast rotating modules, light-duty transmission systems and compact automation devices.
Medium Ratios for Balanced Motion Control
Ratios such as 16:1, 24:1, 36:1 and 64:1 are suitable for applications that require a balance between speed and torque. These options are often useful in electric actuators, automatic adjustment systems, rotary mechanisms and smart equipment.
High Ratios for Low-Speed High-Torque Output
Ratios such as 144:1, 256:1, 576:1 and 864:1 are designed for slow movement and higher torque output. They are suitable for locking mechanisms, precision adjustment modules, valve drives, positioning systems and compact transmission units requiring controlled low-speed motion.
Planetary Gearbox Stage Options
According to the technical data, the gearbox can be configured with 1-stage, 2-stage, 3-stage and 4-stage planetary reduction structures. Different stages provide different speed reduction and torque output levels.
A 1-stage gearbox is shorter and suitable for higher output speed. A 2-stage or 3-stage gearbox provides a stronger reduction ratio for applications needing more torque. A 4-stage gearbox is suitable for very low speed and high torque applications, but the total motor length becomes longer.
This gives OEM engineers more freedom to balance installation space, torque requirement, speed range and gearbox length.
Control and Wiring Features
5-Pin Wiring for Direction, Alarm and Speed Signal
This motor includes a 5-pin wiring definition shown in the technical drawing. The representative pin functions include:
PIN 1 Red: +24VDC
The red wire is used for the positive 24V DC power supply.
PIN 2 Green: F/R Direction Control
The green wire is used for forward and reverse direction control. This is useful for actuator systems, positioning modules and automatic equipment that requires bidirectional movement.
PIN 3 Black: GND
The black wire is the ground connection.
PIN 4 Blue: Alarm Signal
The blue wire provides an alarm signal function. This can help the equipment detect abnormal motor or controller status, depending on the control design.
PIN 5 Yellow: SV Speed Signal
The yellow wire provides a speed signal output. This is useful for systems that require speed feedback, monitoring or basic closed-loop control.
Suitable for OEM Control Integration
The wiring design makes this motor more than a simple gear motor. It can be integrated into OEM control systems where the motor needs direction switching, speed monitoring and alarm feedback. This is useful for intelligent machinery, automation modules and equipment requiring predictable motion control.
For best performance, customers should confirm controller compatibility, signal voltage, wiring definition and control logic before sample testing.
Engineering Selection Notes
Select the Gear Ratio by Final Output Speed
The first step in choosing a brushless planetary gear motor is confirming the required final output speed. A lower reduction ratio gives faster output speed, while a higher reduction ratio gives slower speed and higher torque.
For example, fast rotating applications may choose 3.5:1 or 6:1, while slow actuator movement may require 144:1 or higher. Modar Motor can help calculate the suitable ratio based on the target output speed.
Confirm Torque Requirement and Safety Margin
The required torque should include normal working torque, startup torque and possible peak load. For equipment with frequent start-stop operation, reverse movement or impact load, the selected gearbox should have enough torque margin.
The representative torque range reaches up to approximately 56.7N·m under high reduction ratio, but the final selection should consider working time, gearbox strength, load type and expected lifetime.
Check Controller and Signal Compatibility
Because this is a brushless gear motor with control wiring, the controller should match the motor’s voltage, current, direction signal, alarm output and speed feedback signal. Customers should provide controller information or control requirements during the selection stage.
Consider Gearbox Backlash for Positioning Applications
Planetary gearboxes are compact and efficient, but backlash should still be considered when the motor is used for precision positioning. If the application requires accurate angular positioning or high repeatability, backlash requirements should be discussed before sample confirmation.
Review Duty Cycle and Heat Rise
For continuous operation or high-load intermittent operation, heat rise should be evaluated carefully. Customers should provide load torque, working time, stop time, ambient temperature and installation environment so that the motor can be matched correctly.
Customization Options
Gear Ratio Customization
The planetary gearbox can be selected according to the required output speed and torque. Representative ratios include 3.5, 4, 6, 16, 24, 36, 64, 144, 256, 576 and 864. Other ratio options may be evaluated based on project requirements.
Output Shaft Customization
The output shaft can be customized with different shaft length, diameter, flat shaft, D-cut shaft, threaded shaft, keyway shaft, extended shaft or special machining. This helps the motor connect with couplings, gears, pulleys, lead screws or customer-designed mechanical parts.
Mounting Interface Customization
The gearbox front flange, mounting holes, locating diameter and housing structure can be customized to match the customer's equipment design.
Wiring and Connector Customization
Wire length, connector type, pin definition, cable outlet direction and signal wire arrangement can be customized according to the customer's controller and assembly process.
Voltage, Speed and Torque Customization
Although the representative model is based on 24V DC, Modar Motor can evaluate customized voltage, rated speed, torque and performance requirements according to the customer’s application and order quantity.
Gearbox Length and Stage Selection
Different gearbox stages lead to different overall motor lengths. Customers can choose a shorter gearbox for compact space or a higher-stage gearbox for stronger torque output.
