Brushless motors suit direct drive applications

Brushless motors manufactured by Motion Control Systems (MCS) provide a wide range of flexible motor solutions for frameless direct drive motor applications.

Brushless motors manufactured by Motion Control Systems (MCS) provide a wide range of flexible motor solutions for frameless direct drive motor applications.

The motors are available as either housed or frameless configurations and water cooling can also be accommodated for more demanding applications.

The housed models come with stainless steel shafts and can include any combination of Hall sensors, encoder, or resolver as rotor position feedback devices.

The frameless configuration is supplied as two separate components (rotor and stator) and does not include a shaft, bearings, or endbells.

Frameless motors are integrated directly into the application where the same bearings which support the load also support the motor.

This configuration eliminates shaft, bearings, endbells, and couplings therefore offering reduced volume, weight and complexity.

This also results in improved servo stiffness and quicker response.

Frameless motors can also be supplied with integral Hall sensors, encapsulated windings and thermistors.

Additional position feedback devices such as encoders or resolvers would be added as separate components.

Applications for the MCS motors include underwater propulsion systems, stabilised platforms, hard disk media test stations and precision grinding machines.
