BXR-LE Model datasheet

Product catalog summary

Overview: The BXR-LE Safety Brakes datasheet provides detailed specifications and dimensions for spring-actuated brakes, including models BXR-015-10LE to BXR-050-10LE. It also includes information on the controller model BEM-24ESN7-120N.

Specifications (Brake): The datasheet lists the static friction torque, coil specifications, heat resistance class, lead wire details, maximum rotation speed, rotating part moment of inertia, allowable braking energy rate, total braking energy, armature pull-in and release times, and mass for each brake model. For example, the BXR-015-10LE model has a static friction torque of 0.06 N·m and a maximum rotation speed of 6000 min-1.

Dimensions (Brake): Detailed radial and axial direction dimensions are provided for each model, including rotor hub machining dimensions. The rotor hub can be custom-made or selected from optional products.

Specifications (Controller): The controller model BEM-24ESN7-120N operates with an input voltage of 24 V DC ± 10% and provides an output voltage of 24 V DC initially and 7 V DC constantly. It has a maximum output current of 1.0 A DC at 20 ℃ and 0.8 A DC at 60 ℃. The controller is designed to operate in ambient temperatures ranging from -20 to 60 ℃.

Structure and Timing Chart (Controller): The controller uses PWM control and is structured with lead wires for input and output connections. The timing chart illustrates the voltage output over time, showing an initial 24 V DC output for 0.2 seconds followed by a constant 7 V DC output.

Ordering Information: The datasheet provides guidance on how to place an order, specifying the model size, controller set type, nominal static friction torque, and voltage. Options for rotor hubs include set screw type and press fit type.
