Brake Helical Geared Motor

The Brake Helical Geared Motor combines driving, speed reduction, and braking into a compact unit. The motor delivers input power, the helical gear train reduces shaft speed while multiplying torque, and the direct-mounted electromagnetic brake engages automatically upon power loss to provide immediate stopping or static load holding.

Core Engineering Advantages

Integrated Design
Combines motor, gear reducer, and electromagnetic brake into one dynamic unit, eliminating external alignment issues and reducing overall installation footprint.

Precision Helical Gearing
Ground helical gear teeth distribute tooth engagement loads evenly, delivering power transmission efficiency up to 97% per gear stage while maintaining low operating noise.

Fail-Safe Braking
Spring-applied electromagnetic brake design ensures immediate force application upon power failure, protecting personnel and machinery in emergency scenarios.

Industrial Applications

01/

Belt & Roller Conveyors: Provides smooth speed control and controlled braking on horizontal or inclined material transfer lines.

02/

Material Handling & Hoisting Equipment: Serves transfer cars, turntables, and lifters needing immediate dynamic stopping and holding.

03/

Packaging & Palletizing Machinery: Ideal for indexing drives, wrapping units, and automated packing equipment undergoing repeated cycling.

04/

Automated Production & Assembly Lines: Delivers repeatable positioning across synchronized indexing and manufacturing stations.

05/

Feeder Systems & Agitators: Ensures steady material throughput combined with anti-coasting capabilities.

Motor and Electrical Configuration

Motor Design: Premium copper windings with Class F insulation (155 deg C threshold) and Class B temperature rise, suitable for inverter-fed operation (VFD compatible).

Thermal Protection: PTC thermistors or PTO thermal switches can be integrated into motor windings upon request.

Brake Power Supply: Integrated power supply via internal terminal box rectifiers (AC-to-DC) or external direct DC supply.

Drive Unit Features

Compact Integrated Design: Direct mounting of brake, motor, and gearbox eliminates external couplings, reducing spatial footprint and maintenance points.

Fail-Safe Holding: Automatic brake engagement upon power outage prevents load slippage on inclined or vertical systems.

Low Tooth-Surface Stress: Helical gear geometry distributes mechanical loads across multiple teeth simultaneously, extending operating life.

Step-by-Step Selection Process

Confirm Output Speed: Determine the required shaft speed (rpm) based on machine kinematics.
Determine Output Torque: Calculate actual continuous and peak torque demands under full load.
Select Motor Power: Match input motor kW rating to torque, speed, and service factor requirements.
Choose Gear Ratio: Select the standard reduction ratio closest to the target output speed.

Verify Brake Capacity: Check brake torque against system inertia, stopping time requirements, and cycle frequency.
Confirm Mechanical Interface: Verify shaft diameter, keyway, foot layout, or flange dimensions.
Specify Electrical Requirements: Set motor voltage/frequency and brake control voltage.
Review Environmental Duty: Verify ambient temperature, duty cycle (S1–S6), and IP protection requirements.

Frequently Asked Questions

Q: How do I select the correct brake torque for my drive system?

A: Brake torque should be calculated based on total load inertia, deceleration time, and static holding safety margins. A standard rule of thumb is sizing brake torque to 1.2 - 2.0 x the motor rated torque, depending on load direction and cycling.

Q: Can the brake voltage match our local PLC control system?

A: Yes. We offer standard brake control voltages, including 24V DC for direct PLC signal control, as well as 103V DC, 180V DC, and 230V AC via built-in rectifiers.

Q: Is the integrated brake capable of manual release during power failures?

A: Yes. An optional hand-release lever can be installed on the brake assembly to disengage the brake manually in emergency or power-outage situations.

Q: What is the standard lead time for customized OEM orders?

A: Standard units are dispatched in 10-15 business days. Custom shaft configurations, special voltages, or non-standard flange orders take 20-25 business days.
