Stall Torque Motor – Continuous Torque for Precision Control Applications
What Is a Stall Torque Motor?
A Stall Torque Motor is a specially designed motor capable of producing consistent torque even when the rotor is at a standstill. Unlike conventional motors, these are engineered to operate continuously in a stalled or locked position without overheating or sustaining damage. This makes them ideal for applications requiring constant tension, positioning accuracy, and torque-based control.
At Atlas Electrical, our stall torque motors are built for reliability, smooth control, and long-term performance in demanding automation systems.
Key Features of Stall Torque Motors
1. Continuous Torque at Zero Speed
These motors are optimized to deliver torque continuously without requiring rotor movement, ensuring high stability and load control in stationary conditions.
2. Thermally Stable Design
Designed with superior insulation and thermal management, these motors can handle prolonged stall operation without overheating.
3. Low Inertia Rotor
A specially engineered low-inertia rotor allows for fast response and precise torque regulation, improving process control in sensitive applications.
4. Smooth, Vibration-Free Operation
With advanced windings and low-friction components, stall torque motors ensure ultra-smooth, quiet operation, essential in high-precision environments.
Benefits of Using Stall Torque Motors
1. Ideal for Tension & Torque Control
Perfect for applications like winding, spooling, and tensioning where controlled torque is more important than continuous rotation.
2. Precise Positioning
Stall torque motors can hold a position accurately under load without the need for complex gearboxes or braking systems.
3. Compact and Energy-Efficient
These motors deliver high torque in a compact design while maintaining energy efficiency, minimizing operational costs.
4. Long Operational Life
Made from high-quality materials and equipped with efficient cooling, Atlas stall torque motors offer long service life even under continuous stall conditions.
Applications of Stall Torque Motors
Stall torque motors are widely used in applications that require static torque delivery, such as:
- Textile Winding Machines
- Wire & Foil Tensioning Systems
- Indexing & Positioning Tables
- Printing Presses
- Robotic Arms & Assembly Lines
- Reelers, Coilers & Unwinders
Any machinery that requires torque without rotation or with controlled intermittent movement benefits from a stall torque motor.
How to Choose the Right Stall Torque Motor
Determine Stall Torque Requirements
Know the torque required at standstill and choose a motor rated for that continuous stall performance.
Assess Duty Cycle and Thermal Class
Ensure the motor’s insulation and cooling are suited to your application’s duty cycle (S1 or S3) to prevent overheating during prolonged use.
Confirm Shaft Type and Mounting
Select the correct shaft type (solid or hollow) and mounting configuration (foot, flange, or custom) based on machine compatibility.
Voltage and Control Compatibility
Choose between standard AC single/three-phase motors or versions compatible with torque controllers or variable frequency drives (VFDs).
