Inner Structure

Rotary Motor with Brake

Product Principle

A rotary motor consists of a rotor and stator. The rotor is the load itself or directly connected to the load, and is equipped with permanent magnets. The stator is fixed to the base and contains multiple coils. Based on the electromagnetic principle, energizing the coils generates a rotating magnetic field, which directly drives the permanent magnet rotor to rotate. The rotor speed is determined by the frequency of the applied current, while its position is controlled by the phase of the current.

Product Advantages

1. Efficient heat dissipation

The integrated water-cooling structure efficiently removes heat generated by the motor during continuous operation and high-load conditions. Compared with natural or forced-air cooling, the enhanced thermal management capability helps maintain a more stable operating temperature.

2. Higher continuous torque capability

Improved heat dissipation allows the motor to operate at higher continuous current without excessive temperature rise. This enables higher continuous torque output and makes the motor suitable for applications with sustained heavy-duty operating requirements.

3. Improved thermal stability

Effective temperature control reduces temperature fluctuations during long-duration operation, helping maintain consistent motor characteristics and motion performance. This is especially important for applications where thermal variation can affect positioning accuracy.

4. Reduced thermal deformation

By controlling the heat generated inside the motor more effectively, the water-cooled structure helps reduce thermal expansion and deformation of the motor and surrounding mechanical components. This supports more stable precision during continuous operation.

5. High power density

Efficient liquid cooling allows the motor to handle higher thermal loads within a relatively compact structure. The resulting high power density provides more torque and power without requiring a proportionally larger motor installation space.

Rotary Motor Water Cooled

Water-cooled rotary motors are designed for applications where high continuous torque, high power density, and stable thermal performance are required. The integrated water-cooling structure efficiently removes heat generated by the motor during continuous high-load operation, allowing the motor to maintain a lower and more stable operating temperature compared with conventional cooling methods. Improved thermal management helps reduce temperature-related performance variation and thermal deformation, which is particularly important for precision rotary systems operating over long periods. The enhanced cooling capacity also allows higher continuous current and torque output without requiring a proportional increase in motor size, resulting in higher power density and improved machine efficiency. These motors are well suited for machine tools, high-load rotary tables, continuous processing equipment, semiconductor manufacturing, and other demanding applications requiring long-duration and stable high-performance operation.
