air-water cooling slip ring motor

Air-Water Cooling Slip Ring Motor - Heavy-Duty Industrial Solution

When you need solid power for breaking, cutting, or moving materials in harsh conditions, you need a motor that is made to do the job. Tellhow Shenyang Electric Machine's air-water cooling slip ring motor has a wound rotor design that has been used for years and can handle the biggest industrial problems. Our YRKS series high-voltage motors are made of welded steel, have a flexible design, and can produce 160kW to 10,000kW of power at voltages ranging from 400V to 13,800V. We design solutions that keep your important systems working smoothly. We have over 2,100 specs to choose from and can produce 8 million kW per year.

Why Choose Dual Cooling Technology?

In tough conditions, traditional ways of cooling don't always work. Heat builds up, which makes things less effective and shortens their useful lives.

Our two-pronged method works well to solve this problem.

Through improved circulation paths, air cooling gets rid of the heat in the room. Through carefully designed pathways, water cooling directly cools areas that are very hot.

Three main benefits come from this mix:

Better control of temperature—The method keeps the windings at the right temperature even when they are under heavy loads for a long time. Water tunnels built into the motor case remove heat 15 to 20 percent more effectively than designs that only use air.

Longer useful life—Lower working temperatures lower the stress on the insulator. The time between repair visits is longer for your tools.

Small footprint—Better heat removal lets more power fit in a smaller space. It gives you more output without taking up more room.

The technology changes based on your needs. High heat in the air? The water cycle makes up for it. Different loads? The technology controls itself to keep the temperature stable.

Technical Specifications

Performance Features That Matter

High power for starting with managed current

Your mills and breakers need to have a lot of breaking force. The wound rotor design with external resistance control can produce up to 250% of the maximum power while keeping the inrush current to a minimum. This keeps your electricity system safe and makes related devices less stressed.

Smart defense against heat

PT100 or PTC devices that are built in constantly check the temperatures of the windings. Before things get too bad, the system lets workers know. In wet places, space heaters that are optional keep condensation from forming during idle times.

Building in modules makes upkeep easier.

Important parts can be reached without taking the whole thing apart. Brush parts can be taken out and looked at. The cooling system's screens are cleaned without any downtime. This arrangement makes your servicing windows a lot easier to clean.

Ability to monitor vibrations

The mechanical state is tracked in real time by SPM instruments. Finding instability or bearing problems early on keeps them from becoming fatal. Instead of waiting for problems to happen, you plan repair ahead of time.

Where These Motors Excel

Mining: The high starting power and constant duty rates are good for ball mills, SAG mills, and crushers. The air-water cooling slip ring motor can handle the rough dust and wide temperature changes that are typical in material processes.

Making cement: Rotary kilns, raw mills, and cement mills need to be reliable all the time. Even though process heat transfer happens, the dual cooling system keeps working at the same level.

Metallurgy: Rolling mills, flying shears, and material carriers need to be able to precisely control speed and respond quickly to changes in torque. The shape of the slip ring works well with these changing load patterns.

Water treatment: In city systems, big pumps and fans run all the time with little control. The strong construction and tracking systems make sure that it will work without being watched.

In petrochemical processing, explosion-proof designs are available for compressors and fans that are used in dangerous places. Water-assisted cooling also helps keep the equipment cool.

Frequently Asked Questions

Q:What advantages does water cooling provide compared to air-only designs?

A:Water cooling removes heat approximately four times more efficiently than air due to water's superior thermal conductivity. This allows higher continuous power ratings in the same frame size. You gain more output capacity without expanding your installation footprint. The technology particularly benefits installations in high ambient temperature environments where air cooling effectiveness diminishes.

Q:How complex is the water cooling system maintenance?

A:The system requires minimal attention. Regular maintenance involves checking water quality quarterly, inspecting hoses and connections for leaks, and cleaning filters. Most installations use closed-loop systems with corrosion inhibitors, reducing water quality concerns. Annual thermal imaging helps verify even cooling distribution. Compared to managing heat-related failures, the maintenance burden is minimal.

Q:Can these motors operate if the water cooling system fails?

A:Motors include thermal protection that monitors winding temperatures continuously. If water flow stops, sensors detect rising temperatures and either derate motor output or initiate a controlled shutdown before damage occurs. Emergency air cooling provides limited operation at reduced capacity. The control philosophy prioritizes protecting your equipment investment over maximum output.

Q:What starting method works best for heavy loads?

A:The slip ring design inherently accommodates multiple starting methods. Liquid resistance starters provide the smoothest acceleration for extremely heavy inertial loads. Stepped resistance starting offers simplicity and reliability. For applications requiring frequent starts, soft-start systems minimize mechanical stress. Our engineering team evaluates your specific load characteristics, start frequency, and utility constraints to recommend the optimal approach.

Q:How do I specify the correct motor for my application?

A:Begin with your load requirements: power, speed, torque profile, and duty cycle. Identify environmental factors including ambient temperature, altitude, humidity, and atmospheric contaminants. Consider operational constraints such as available voltage, starting current limitations, and space restrictions. Our application engineers use this information to select frame size, cooling configuration, protection rating, and accessories. Detailed load analysis ensures proper thermal capacity and mechanical sizing.

Q:What documentation comes with each motor?

A:You receive comprehensive technical documentation including dimensioned outline drawings, terminal connection diagrams, foundation and mounting specifications, test reports verifying performance parameters, lubrication schedules, and maintenance procedures. Installation and commissioning guidelines walk your team through proper setup. Spare parts lists with manufacturer part numbers simplify future ordering.
