Packaged Products Benefits Warner Electric Packaged Products come pre-assembled, ready to install right out of the box. Warner Electric Packaged Products consist of a single part number in most cases. One part number to inventory, one part number to track in your engineering system. All Warner Electric packaged products incorporate our Autogap™ mechanism that automatically adjusts for wear. This eliminates the need for maintenance, but more importantly, it ensures the same engagement time cycle after cycle after cycle through the whole life of the unit ensuring consistent product manufacturing...

Packaged Performance Products Electromagnetic Clutches and Brakes oltage/Torque Curve Principle of Operation A key feature of Warner Electric brakes and clutches is the method of actuation. Like an electromagnet, they have two basic parts. A magnetic field is generated as soon as the current flows through the magnet coil. This draws the armature into direct contact with the magnet. The strength of the magnetic field is directly proportional to the amount of current applied. Full range torque control from 0 to 100% is as simple as turning the knob on a light dimmer. The benefits of electric actuation...

Introduction to Packaged Performance Products 11/18

Electrically Released brakes fall within two categories: Static Engage and Dynamic Stopping. Static engage brakes are similar in function to an automotive parking brake: while they can be used to stop in an emergency, they are primarily to hold a load stationary after the load is already stopped. A static engage brake that is used as an active stopping brake at high cycle rate will wear out quickly. Common industrial static applications are vertical or incline conveyors. The drive and motor may decelerate the conveyor to a stop and then engage the brake to hold the load in position. A second...

Spring-Set Electrically Released Brakes Spring Set Brakes Robotics ERS Brakes can position and hold robotic equipment. Emergency braking in the event of power loss can prevent damage to equipment. Automated Material Handling Systems ERS Brakes hold rollers and lift mechanisms in place, and lock drive wheels in place. Medical Equipment ERS brakes are used as parking brakes in wheelchairs and holding brakes in medical apparatus such as mammography and cat scan equipment. Overhead Door The ERD can be used in conjunction with a photo eye. In this application, whenever the light beam is broken, voltage...
