80mm Brushless Planetary Gear Motor | 24V High Torque BLDC Gearmotor

The 80mm brushless planetary gear motor is a high-torque 24V BLDC gearmotor engineered for OEM applications that require stronger load capacity, controlled output speed and long operating life. By combining a high-output brushless DC motor with a multi-stage planetary gearbox, this series is designed to deliver substantially more torque than smaller gearmotor platforms while still maintaining a compact integrated structure.

According to the representative technical parameters, the motor is based on a 24V brushless motor platform and supports gearbox ratios from approximately 4.29:1 to 836.86:1. Depending on the selected ratio and stage configuration, the final output speed can range from about 3rpm to 583rpm, while output torque can range from approximately 3.1N·m to 439.3N·m. This makes the product highly suitable for heavier-duty motion systems that need slower output speed and much higher torque.

80mm brushless planetary gear motor – Product Overview

80mm brushless gear motor


80mm brushless planetary gear motor for Heavy-Load Output

The 80mm brushless planetary gear motor is designed for applications where smaller compact gearmotors no longer provide enough torque reserve. With a larger gearbox and stronger brushless motor platform, this series can handle more demanding mechanical loads while delivering smoother control and longer service life than a typical brushed gear motor.

For OEM designers, this means 80mm brushless planetary gear motor can be used in systems that require reliable torque transmission over long operating cycles. It is particularly suitable for equipment where output force, gearbox durability and low-speed controlled movement are more important than ultra-compact size.

24V Brushless Motor Platform with Integrated Reduction Drive

The representative base motor model shown in the technical chart is X88BLDC045, a 24V brushless DC motor. Before gearbox reduction, the motor provides:

  • No-load current: approximately 1.77A

  • No-load speed: approximately 2941rpm

  • Rated current: approximately 11.79A

  • Rated speed: approximately 2500rpm

  • Rated torque: approximately 0.8N·m

  • Motor length: approximately 86mm

This base motor is then paired with a planetary reduction gearbox to generate a wide range of final output speed and torque combinations. The integrated structure allows engineers to use one motor platform across many application types simply by changing the gearbox ratio and stage count.

Reduction Ratios from 4.29 to 836.86

One of the core advantages of 80mm brushless planetary gear motor is the wide ratio selection. The representative table includes the following reduction ratios:

4.29, 5.18, 6.75, 18.37, 28.93, 34.98, 78.72, 149.90, 236.1, 531.34 and 836.86

This broad ratio window allows the motor to support very different operating profiles.

Low Ratios for Faster Mechanical Output

Ratios such as 4.29:1, 5.18:1 and 6.75:1 are suitable for applications that still require relatively fast shaft speed but need more torque than a direct-drive motor can deliver.

Typical examples include rotating rollers, drive wheels for auxiliary systems, faster transfer modules and compact industrial transmission assemblies.

Mid Ratios for Balanced Torque and Speed

Ratios such as 18.37:1, 28.93:1 and 34.98:1 provide a more balanced output. These are often selected for electric actuators, rotary indexing systems, positioning mechanisms and general industrial automation equipment.

High Ratios for Slow and Powerful Motion

Ratios such as 78.72:1, 149.90:1, 236.1:1, 531.34:1 and 836.86:1 are intended for low-speed, high-torque motion. These configurations are suitable for lifting modules, locking mechanisms, heavy positioning systems, turntable drives and other motion systems where torque matters more than speed.

Multi-Stage Planetary Gearbox Structure

The gearbox can be configured with 1-stage, 2-stage, 3-stage or 4-stage reduction structures. Each stage combination changes overall length, torque capability and output speed.

1-Stage Gearbox

A 1-stage gearbox is more compact and supports higher output speed. In the representative table, the 1-stage configuration corresponds to shorter total length and is appropriate for faster applications with lower reduction demand.

2-Stage Gearbox

A 2-stage gearbox provides stronger reduction while keeping the assembly relatively compact. It is suitable for mid-speed automation modules, drive units and mechanical motion systems requiring more torque.

3-Stage Gearbox

A 3-stage gearbox is ideal when the equipment needs lower shaft speed and significantly higher torque. This is common in industrial adjustment mechanisms, medium-duty lifting systems and heavy automation modules.

4-Stage Gearbox

A 4-stage gearbox is designed for very low output speed and very high torque. This is the best choice for applications like slow-positioning drive systems, gate operators, heavy-duty rotary systems and compact power reduction modules.


Representative Performance Range

Output Speed Window

Based on the representative chart, the motor can provide output speed from approximately:

  • 583rpm at lower reduction ratios

  • down to about 3rpm at the highest reduction ratios

This makes 80mm brushless planetary gear motor series suitable for both moderate-speed industrial motion and extremely slow controlled movement.

Output Torque Window

The representative output torque range spans from approximately:

  • 3.1N·m

  • up to 439.3N·m

This is a major reason why the 80mm brushless planetary gear motor platform stands out from smaller BLDC planetary gear motors. It is far better suited for applications where substantial torque multiplication is needed.

Gearmotor Length Options

Total gearmotor length varies according to gearbox stage. Representative lengths include approximately:

  • 140.5mm

  • 162mm

  • 183.5mm

  • 205mm

This allows OEM engineers to balance installation space and output performance when selecting a suitable configuration.


Engineering Selection Notes

Start with the Required Output Speed

When choosing a planetary BLDC gearmotor, the first design step is identifying the required final output speed. A faster application generally needs a lower ratio, while a slow and force-focused application needs a higher ratio.

For example:

  • faster rotating modules may use 4.29:1 to 6.75:1

  • balanced actuator systems may use 18.37:1 to 34.98:1

  • high-torque slow-motion systems may use 78.72:1 and above

Check Real Working Torque, Not Just Nominal Torque

The correct model should be selected using actual working torque, not only the table’s maximum torque values. Engineers should include:

  • normal running torque

  • startup torque

  • acceleration load

  • friction load

  • peak load or overload condition

A proper safety margin helps improve gearbox life and operational reliability.

Match the Motor with a Suitable BLDC Controller

Because this is a brushless DC gear motor, it must be matched with an appropriate BLDC controller. The controller should support:

  • 24V DC input

  • required current range

  • Hall signal input

  • forward/reverse control if needed

  • speed regulation method

  • braking or protection logic if required

Correct controller matching is especially important in heavy-load applications.

Consider Backlash and Positioning Accuracy

Planetary gearboxes are compact and efficient, but like all mechanical reduction systems, they have backlash. For applications such as indexing, alignment or precise angular control, backlash tolerance should be discussed during model selection.

Review Duty Cycle and Thermal Conditions

The final choice should also consider:

  • continuous or intermittent operation

  • ambient temperature

  • enclosure ventilation

  • mounting orientation

  • load duration

  • frequent reversing or start-stop motion

These factors affect both motor heat rise and gearbox service life.


Motor Wiring and Control Features

Hall Sensor Motor Connection

The 80mm brushless planetary gear motor drawing shows a standard motor connection diagram with Hall sensor wiring and motor phase wiring. This type of configuration is widely used in BLDC systems because it improves:

  • startup stability

  • rotor position detection

  • commutation accuracy

  • speed control consistency

Suitable for Closed-Loop and Controlled Motion Applications

Because the motor includes Hall-related wiring, 80mm brushless planetary gear motor is suitable for systems that need more controlled output than a simple open-loop brushed motor. This is useful in smart devices, automation equipment, robotic modules and industrial machinery where predictable motion is important.


Customization Options

  • round shaft

  • D-cut shaft

  • flat shaft

  • threaded shaft

  • keyway shaft
