In today's heavy industrial environment, precise speed regulation and torque control are critical for safe, smooth, and efficient electrical machinery operation. Moving machinery and heavy-duty motors require dependable resistance units that can handle massive electrical currents while dissipating generated heat safely. One of the most essential solutions for these application demands is the industrial Resistance Box.
Axiscranes is a premier Resistance Box Manufacturer in India, delivering high-grade resistance boxes engineered for optimal thermal dissipation, precise motor control, safe dynamic braking, and long service life. Our resistance boxes are widely used in overhead cranes, heavy machinery, slip-ring motors, electric locomotives, and diverse industrial automation systems where efficiency, heat resistance, and reliability are absolute priorities.
What Is a Resistance Box?
A Resistance Box is an electrical control device designed to limit current, control speed, and dissipate excess kinetic energy as heat in high-power electric motors. By inserting specific resistance values into the rotor or stator circuits, it provides starting torque control, smooth acceleration, dynamic braking, and overall electrical protection for industrial machinery.
It is widely used across different industries for:
- EOT crane motor speed and torque regulation
- Slip-ring motor starting and speed control
- Dynamic braking applications for drives and heavy hoists
- Load testing and current limiting in power sectors
Types of Resistance Boxes
1. Stainless Steel Grid Resistance Box
Engineered for high-current and continuous duty applications, stainless steel grid resistance boxes offer exceptional corrosion resistance, superior heat dissipation, and long-lasting performance under extreme thermal loads.
2. Punched Grid Resistance Box
Ideal for heavy-duty crane duty cycles, punched grid designs provide robust mechanical strength, consistent ohmic values, and shock-resistant operational capabilities in rugged industrial settings.
3. Wire Wound Resistance Box
Designed for moderate power and lower current applications, wire wound resistance boxes deliver high accuracy, excellent thermal stability, and fine-tuned control for specialized machinery drives.
