ECLIPSE PRODUCTS TM TECHNICAL DATA SHEET Eclipse Servo Motor Brake Flange Mounted, Spring Engaged, Air Released Split Hub, Clamp Collar Sizes, 3, 4, and 5
ECLIPSE TM SERVO MOTOR BRAKE The Eclipse Servo Motor Brake family now includes a line of spring-engaged servo motor brakes equipped with a split hub, clamp collar for attachment to the servo motor shaft. With superior torque outputs, these brakes provide rugged durability for dynamic stopping applications. Eclipse brakes offer consistent long-lasting performance with no maintenance needed. Nexen s servo motor brakes run with at least 0-50% more torque than competitive brakes and provide safe, simple operation. The easy-to-use flange-mounted Eclipse brakes solve many of the problems associated with brake motors. Use them with standard motors for brake motor functionality and offthe-self availability. The servo brakes are available in a variety of input and output flange/shaft combinations and have many features to increase the safety of your machines. Servo Motor Brake with NEMA output flange Simple installation with split hub, shaft collar Spring engaged, air released True pilot mounting High torque when compared to electric brakes Zero backlash for precision holding Bidirectional braking Long facing life Cool operation, high efficiency, less energy consumption Designed for horizontal or vertical applications Strong enough to stall the servo motor Quick, safe emergency stopping and holding Ideal for use with linear ball-screw stages and belt drives Field Serviceable Low inertia Output flange replicates motor flange Quick exhaust valve included High torsional rigidity High overhung load capacity Meets IP67 dust and waterproof standards Optional Soleniod Valve allows for: Visual disengagement indication Manual disengagement on valve Simple connections with 4VDC control and 80 PSIG shop air Remains engaged and holds load during motor change outs ALTERNATIVES AVAILABLE Contact Nexen : For reduced torque models and other sizes not shown. For information on future models that will cover a variety of servo motor families as well as all popular servo motor manufacturers. For other output flange options. For optional solenoid valve. Pneumatic units accept an optional solenoid valve (normally closed) controlled by 4VDC at 04 ma. Solenoid valves are fitted with 8" flying leads standard. To order the solenoid valve (optional), please refer to Nexen product #964650. See Back page for contact information.
