ElectroMagnetic Clutches

ElectroMagnetic clutchElectromagnetic clutches operate electrically and transmit torque mechanically. Generally, electromagnetic clutches are best for remote operation because there are no linkages necessary to control its engagement. Electromagnetic clutches have fast and smooth operations. Energy disperses as heat in the electromagnetic actuator when the clutch is engaged, and thus the maximum operating temperature of the clutch is limited by the electromagnet's insulation temperature rating.

W.M. Berg offers the best electromagnetic clutches and will customize them to suit your individual needs. W.M. Berg, one of the world's largest suppliers of precision manufacturing parts, is dedicated to quality and customer satisfaction. W.M. Berg carries an electromagnetic clutch with 0.800 torque rating. W.M. Berg also carries wafer magnetic clutches, with three available options: output shaft at both ends, output shaft at X end, and output shaft at Y end. All wafer magnetic clutches from W.M. Berg have 32 torque rating. W.M. Berg supplies the best quality and best price electro-mechanical clutches and is committed to satisfying your needs.

Stepper Motors

stepper motorsW.M. Berg has a variety of stepper motors available to fit your individual needs. Our highly qualified engineers will customize the stepper motors to your specific application and will work with you to ensure the appropriate stepper motor is selected. Stepper motors are unique because they are constant power devices. A stepper motor is a brushless DC electric motor that divides a full rotation into multiple steps. The position of the motor can be controlled precisely without a feedback mechanism as long as the motor is sensibly sized to the individual application. Stepper motors have multiple toothed electromagnets that circle around a central gear shaped piece of iron. The electromagnets are energized by an external control circuit. To make the motor shaft turn, one electromagnet is first given power, attracting the gear's teeth to the electromagnet's teeth. When the teeth align, they are slightly offset from the next electromagnet. When the next electromagnet is turned on and the first is turned off, the gear rotates to align with the next electromagnet. This continues for all other electromagnets, completing each step, as a slight rotation is called.

W.M. Berg engineers will work with you to ensure you do not encounter negative effects of vibration. W.M. Berg creates high quality stepper motors and offers a variety of stepper motors with a variety of torque ratings and styles, including standard stepper motors, programmable stepper motors, and open frame stepper motor drives. Two of W.M. Berg's standard options are microstepping options as well. W.M. Berg is one of the world's largest precision parts manufacturers and will find a solution to your stepper motor needs at the best price, with the highest quality.

ElectroMagnetic Brakes

Direct Acting Brake

Direct acting brake, electromagneticW.M. Berg offers a variety of brakes. The first form of brakes is a direct acting brake. A direct acting brake works through an internal electromagnet within the brake. This internal electromagnet works by pulling back the pressure plate while the motor is running and the power is engaged. The pulling back of the pressure plate allows the friction discs and the motor shaft to rotate freely. When power to the motor is disengaged, the electromagnet releases, which stops the rotating discs and prevents the motor shaft from turning. A direct acting brake has only one moving part, and this promotes longevity of the product, as there are no complicated parts to break or fail. W.M. Berg supplies high quality engineered direct acting brakes with a spring set design. These direct acting brakes are available in multiple torque ratings.

Hysteresis Brakes

ElectroMagnetic Hysteresis BrakesW.M. Berg engineers the best quality hysteresis brakes. A hysteresis brake is an eddy current absorber that puts the electromagnet coils inside a vented and ribbed cylinder. The cylinder is then rotated instead of having a disc rotating between the electromagnets. Hysteresis brakes produce torque through a magnetic air gap without use of magnetic particles or friction parts. This means smoother operations, longevity, ease of control, ease of repetition, and lower maintenance requirements. The hysteresis brakes are perfect for precision manufacturing and applications. There are many applications, including sheeting, material process applications, printing and labeling, and many others. W.M. Berg is dedicated to quality and is happy to offer custom engineered solutions to fit your individual needs.

Wafer Spring Brake

Wafer Spring BrakesW.M. Berg also engineers high quality wafer spring brakes. W.M. Berg offers three distinct options for wafer spring breaks, all with torque ratings of 12. The three high quality options are output shaft at both ends, output shaft at X end, and output shaft and Y end. W.M. Berg is committed to quality and to providing you the wafer spring brake you require. Custom engineered wafer spring brakes can be created by W.M. Berg quality technicians and engineers. W.M. Berg will work with you to ensure you receive the best quality wafer spring brakes at the best price.

ElectroMechanical Hubs

MultiAxis HubW.M. Berg provides high quality hubs. The SMHUB-8 Multi-Axis Hub allows up to 8 indexer drives to be controlled from a single RS-232 serial port. Each indexer drive has a unique address from the port it is connected to, which decreases the cost of the drive and of configuring or replacing drives. You can select the power level and features you require for each axis of your application, which means you do not spend extra money to run power levels above your specific needs. The SMHUB-8 from W.M. Berg is designed to save you money and provide the best quality and utility. You do not need a separate power supply to run the SMHUB-8, as the hub is powered by the drive connected to the first port. There are 50 included commands in the W.M. Berg SMHUB-8 command language which allows the hosting PC or PLC to create relative, absolute and homing moves, make status inquiries, sample inputs, set outputs, among many more applications. The W.M. Berg hub will provide you a cost effective yet high quality solution for your application, and as is true for all W.M. Berg precision manufacturing parts, customizable solutions are available to better fit your individual needs.
