62mm / 78mm DC Planetary Geared Motor: Heavy-Duty Force

The 62mm and 78mm DC Planetary Geared Motors represent the heavy-duty segment of brushed DC geared solutions, utilizing large frame DC motors coupled with robust planetary gearheads.

This combination is designed for extremely high torque demands (often exceeding 100 Nm) common in industrial mobility, medical lifts, and heavy automation. The large brushed DC motor provides the sheer power, simple reversibility, and high starting torque required, while the planetary gearbox handles the substantial load multiplication and output forces. The design prioritizes rugged mechanical strength and continuous high-force output, making them essential components in demanding industrial machinery.

Integrated Production and Customization Workflow

Production involves rigorous non-destructive testing (NDT) of critical gear components and dynamic load testing on a high-torque dynamometer to verify maximum continuous and peak torque ratings.

Brake Integration: Pre-assembling and testing the integrated electromagnetic brake unit to ensure it meets the required safety holding torque rating.
Custom Motor Winding: Designing the motor winding to match specific industrial battery voltages (e.g., 36V, 48V) for maximum efficiency and power output.
IP Rating Upgrade: Providing robust sealing (up to IP65) for motors used in outdoor or harsh cleaning environments (e.g., floor scrubbers).
Output Interface: Customizing the output shaft with a specialized spline, keyway, or bolt pattern for direct integration with the final drive mechanism (e.g., wheel hub).

Service & Support

Technical Advantages and Core Design Features

Extreme Torque Output: Capable of handling massive continuous and peak torque requirements due to the robust gear stages and large motor size.

Integrated Braking Options: Large electromagnetic spring-applied brakes can be seamlessly integrated to provide reliable holding for vertical or vehicle applications.
High Thermal Capacity: Large motor and gearbox housing act as excellent heat sinks, allowing for higher continuous power output.
Simple PWM Control: Utilizes mature and cost-effective PWM controllers for speed and torque regulation.

Frequently Asked Questions

Common Inquiries Regarding Large DC Planetary Geared Motors

Q: How do you manage the heat generated by the brushes in such a high-power DC motor?
A: Heat management is achieved through high-efficiency motor windings, large brush/commutator surface area, and the large metal housing, often paired with optional external cooling fins or forced-air cooling in the most demanding applications.

Q: Are these units suitable for direct wheel drive in electric vehicles?
A: Yes. They are commonly used in AGVs and mobility scooters. The design must account for the high radial loads (weight of the vehicle) and axial loads (cornering/bumps) by specifying appropriate output bearings and mounting flanges.

Q: How critical is the mounting for a high-torque gearbox?
A: Extremely critical. The high output torque generates large reaction forces on the mounting flange. The flange and mounting bolts must be correctly specified to prevent housing breakage or bolt shear under peak torque conditions.

Advanced Material Selection Guide

Gears: Heavy-duty, precision-ground, carburized, and hardened alloy steel (e.g., 42CrMo) to handle the highest possible peak torque stress.

Output Bearings: Double-row angular contact ball bearings or tapered roller bearings are often used to manage the extreme radial and axial loads of wheel drives.

Brush System: High-density, high-copper-content carbon brushes for reliable, low-resistance current transfer at high power levels.
