Structure
The structure of planetary gearbox with motor generally follows a specific arrangement to achieve its functionality
Motor
- Core component that provides the rotational power.
- brushless motor or brushed motor.
Sun Gear
- Center of gearbox, driven by input shaft.
- Transfers motion to the planet gears.
Planet Gears
- Planet gears meshing with sun and ring.
- Carrier-mounted ensures even load distribution & high torque.
Planet Carrier
- Secures planet gears, enabling free rotation.
- Transfers combined torque to output shaft.
Ring Gear
- Large gear encircles and engages planet gears.
- Fixed or rotating, adjusts gear ratio.
Output Shaft
- Connected to the planet carrier.
- Delivers the output power to the driven equipment.
By Current
Choice between AC and DC planetary gear motors depends onpower source availability, speed control needs, size constraints, and operational environment.
DC
- Power Source: DC planetary gear motors, powered by DC electricity, excel in precise speed control, variable speed, and battery applications.
- Motor Type: Typically uses brushed DC or BLDC motors, BLDCs are more efficient, quieter, and last longer than brushed.
- Control and Speed: Easily controlled with simple circuits; offers precise speed regulation and responsiveness.
AC
- Power Source: AC planetary gear motors, powered by AC electricity, are ideal for continuous operation and high-power industrial applications.
- Motor Type: AC induction motors are robust, reliable for continuous operation, while AC synchronous motors offer precise speed control.
- Control and Speed: Typically controlled with complex systems; speed control uses variable frequency drives (VFDs) or other AC methods.
By Types
Both brushed and BLDC combined with planetary gearboxes provide high torque, compact size, and Increase motor torque and reduce speed.
Brushless
- Brushless planetary gear motor features electronic commutation with magnets, eliminating brushes for reduced wear.
- With a diameter of 20mm-28mm, it operates at a rated speed of 5rpm-2000rpm and delivers torque between 500mNm and 4000mNm.
- It offers longer lifespan, low maintenance, and enhanced speed and torque control.
Brushed
- Brushed planetary gear motor features mechanical commutation with brushes that wear out over time.
- It has a diameter range of 6mm to 42mm, a rated speed of 4rpm to 12,000rpm, and torque between 1mNm and 160,000mNm.
- It provides simpler control but has a shorter lifespan, needing regular brush replacement.
