Electromagnetic clutch and brake developer, Warner Electric, has launched the Gen4 range of spring-operated, electromagnetically released brakes. It claimed they provide a rugged and reliable solution for the control of rotating machinery in a diverse range of applications.

The company said the range has been designed to suit demanding, high speed applications, offering high torque density, low response time and a 100 per cent duty cycle at rated torque. The brake is available in single or dual disc variants in five standard disc diameters with nominal torques ranging from 200 to 3,200 Nm. All but the largest sizes in the range are suitable for operating speeds up to 4,700 min-1. The Gen4 brakes incorporate wear compensation features for long life, and a built-in wear sensor means users can monitor brake condition during operation. Integration with sophisticated machine control systems is further assisted by a release detection microswitch, and the brakes are built with holes to mount a rotatory encoder for speed monitoring.

The Gen4 brakes are protected to the IP67 standard for moisture and dust ingress and rated to operate in ambient temperatures from -40°C to +50°C and up to 100 % humidity. They are available with marine certification on request.

Warner offers a comprehensive range of configuration options to allow users to tailor the Gen4 brakes to their applications. Those options include single or dual voltage operation, radial or axial cable output, the addition of an internal or external hand lever, as well as a multiple disc configuration. The units can be manufactured with alternative hub dimensions to suit user requirements and standard EN 50347 mounting flanges can also be provided. Options to suit demanding operating environments include the incorporation of an ant-condensation heater and an IP67-rated breather.
