BL57 Worm Geared BLDC Motor: High Torque, Maintenance-Free Right-Angle Drive

The BL57 Worm Geared Brushless DC Motor integrates a powerful 57mm (NEMA 23 size) BLDC motor with a robust right-angle worm gear reducer.

This combination is engineered for industrial applications requiring sustained high torque, zero-maintenance, and the essential self-locking feature inherent in high-ratio worm drives. The BLDC technology ensures an extended lifespan far exceeding brushed options, making it the preferred choice for continuous, difficult-to-access machinery where the non-back-drivable function is critical for safety and holding position against gravity or load forces.

Introduction

Detailed Parameters and Performance Data

RETEK: Industrial Grade Holding Power and Reliability

Suzhou Retek Electric Technology Co., Ltd. provides the BL57 worm geared solution for heavy-duty industrial positioners and actuators. Our focus is on maximizing the life of the worm gear by using high-quality bronze or aluminum bronze worm wheels and precision-ground steel worms. We design the system for effective heat dissipation, critical for worm drives, ensuring the continuous operating temperature remains within limits despite the sliding friction losses. This unit is highly valued for automated systems that require safe, set-and-forget positioning.

Applications

Advanced Technology Highlights

Heavy-Duty Self-Locking Applications for BL57 Worm Geared Motors

Industrial Lifting Platforms: Actuators for scissor lifts, material hoists, and ergonomic workstations requiring continuous, static load holding. Challenge: Safety holding without external brakes.

Additional Information

Supplementary Details & Notes

Integrated Production and Customization Workflow

Manufacturing includes precise backlash tuning and a break-in period under load to ensure optimal worm wheel seating and guaranteed self-locking function under test conditions.

Custom Shaft Configuration: Offering hollow-bore, double-ended, or integrated mounting pin shafts tailored for direct-drive application integration.
Environmental Coating: Applying industrial-grade epoxy or powder coatings to the housing for enhanced corrosion resistance in harsh outdoor or chemical environments.
Voltage/Winding Match: Customizing the BLDC motor winding to perfectly match high-voltage industrial DC power supplies (e.g., 48V, 60V).
Encoder/Limit Switch: Factory installation of end-of-travel limit switches or output-shaft position encoders for fully integrated control.

Service & Support

Technical Advantages and Core Design Features

True Maintenance-Free Operation: The BLDC input motor eliminates brush wear, offering extreme longevity, often exceeding 20,000 hours.
Positive Self-Locking: High-ratio versions guarantee the output shaft cannot be back-driven, providing a high level of safety and positional integrity.
High Torque Density: Delivers substantial output torque in a compact, right-angle format, optimizing machine layout.
Smooth and Quiet Running: The large worm wheel and optimized BLDC commutation result in lower vibration and acoustic noise than spur gear systems of comparable power.
High IP Rating Ready: The sealed design is easily upgraded to high IP ratings (e.g., IP65) for reliable outdoor or washdown applications.

Frequently Asked Questions

Common Inquiries Regarding BL57 Worm Geared Motors

Q: Can I use this motor to adjust speed quickly, similar to a servo?
A: No. The inherent friction of the worm gear makes rapid acceleration/deceleration highly inefficient and generates excessive heat. Worm geared motors are best suited for slow-speed, high-torque positioning tasks.

Q: Is there a trade-off between self-locking and efficiency?
A: Yes. The condition for self-locking is achieved when the worm lead angle is very small, which results in very high friction and lower efficiency. If you need reversibility (no self-locking) and higher efficiency, you must choose a low-ratio worm or a different gear type (e.g., planetary).

Q: How can I monitor the actual position of the output shaft?
A: We recommend installing an absolute or incremental encoder on the output shaft (after the gearbox) for direct position verification, especially in high-ratio systems where input shaft error is greatly magnified.

Resources

Advanced Material Selection Guide

Worm Wheel: High-quality bronze alloy (e.g., CuSn12) to maximize contact life and minimize wear against the hardened steel worm.

Lubrication: High-grade synthetic gear oil or grease specified for worm drives, selected for its pressure-bearing capability and high thermal stability.

Housing: Heavy-duty, often ribbed cast aluminum housing to provide maximum surface area for passive heat dissipation.
