1 LINEAR MOTION CONTROL PRODUCTS Servomotor Brakes Eclipse Servomotor Brake The Eclipse Servomotor Brake family is a springengaged servomotor brakes equipped with a split hub, clamp collar for attachment to the servomotor shaft. With superior torque outputs, these brakes provide rugged durability for dynamic stopping applications. Eclipse brakes offer consistent longlasting performance with no maintenance needed. Nexen s servomotor brakes deliver at least 20 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 off-the-self availability. Nexen offers servomotor brakes in a variety of input and output flange/shaft combinations, all designed to increase the safety of your machines. 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 a servomotor Quick, safe emergency stopping and holding Remains engaged and holds load during motor change-outs 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 Solenoid Valve allows for: Visual disengagement indication Manual disengagement on valve Simple connections with 24VDC control and 80 PSIG shop air Specify product No

8 Servomotor Brake Selection Example The brake mounted between a servo motor and a 145TC-flanged gearbox is required to perform a dynamic stop of a gantry moving in the X axis, within (5) seconds. The 18 foot long gantry travels at 120 inches per second and carries a 3500 pound load. The driving/stopping forces are driven through a 40 tooth, 14mm pitch sprocket. Brake Stop Time Calculations Given: Gearbox Ratio= 12.19:1 Sprocket Diameter= 7.0 inches, 3.50 inch radius Velocity= 120 feet per second or feet per minute Weight of loaded gantry= 3500 pounds Required Stop Time= 5 seconds Rated Brake Torque= 200 inch pounds (1) Energy per Stop (E) = ½ MV 2 Mass (M) = W/32.2 W=Weight of the load 32.2=Acceleration of gravity (3) Force (F) in pounds exerted on the drive sprocket (Torque (Tgb) at the output side of the gearbox divided by the Sprocket Radius) F = 2438/3.5 = 697 lbs M = 3500/32.2 = 9 lbs E = 1/2(9) 2 = 5435 ft-lbs (2) Torque (Tgb) at the output side of the gearbox (Rated Brake Torque x Gearbox Ratio) Tgb = 200 x = 2438 in-lb (4) Stop Time (t) = Velocity (V) of the gantry divided by the Deceleration Rate (a) in feet per second squared a = 32.2 (F)/W V = Velocity in feet per minute = a = 32.2 (697)/ 3500 = 6.4 f/s^2 t = /6.4 = 1.6 seconds Recommended Eclipse TM Servomotor Brake Size 4, 200 inch pound rated brake Input Flange Data: Bolt Circle: 165 mm, Bore: 24mm Output Flange and Shaft Data: NEMA 145TC In accordance with Nexen s established policy of constant product improvement, the specifications contained in this document are subject to change without notice.
