Spring-Actuated Brakes

Emergency braking in power outages, long holds of stopped positions

 

These are electromagnetic brakes that are actuated by the force of a spring when electricity is not flowing. They provide excellent performance in emergency braking when power goes out, holding stopped positions for long periods of time, preventing machinery from coasting down, and the like. They provide advantages such as quiet braking, long service life, high torque from a compact form factor, reliable and stable braking power, and manual release. Spring-actuated brakes comes in two types, braking and holding.

Applications :

Various motors/Multi-joint robots/Actuators/Machine tools/Forklifts/Aerial vehicles/Hoists/Mobility scooters/Electric shutters/Medical machinery/Wind power generators

BXR LE Model

This is the Spring-Actuated type brake which takes assumption that combining a special controller for controlling the electrical energy required for maintaining the electrical energy and the released state necessary for overcoming the spring pressing force in the initial releasing operation stage of the brake. Through this kind of design, it enabled the provision of various benefits such as energy-saving,low heat generation and compactness achievement. Basic Specifications Brake torque : 0.06N･m～3.20N･m Outer diameter of brake : 26 mm to 71 mm Operating temperature : Brake -10℃～40℃、Controller -20℃～60℃

BXW Models

A total of four types are available: three types with the same dimensions but different load torques and one type with specifications and dimensions matched to compact servo motors [ ]40, [ ]60, and [ ]80.Select the one that best matches your application and life cycle. All types satisfy the rated torque values from the initial use, so the customer does not need to break them in. Basic Specifications Brake torque : 0.12 N･m to 5.2 N･m Outer diameter of brake : 37 mm to 75 mm Operating temperature : -10℃ to 40℃

BXR Models

Only two-thirds the thickness of our older models, they do away with projections that get in the way. These brakes are dedicated for holding and emergency braking while allowing for space-saving mountings.Their major point is the much lighter rotor, which successfully reduces racing wear dramatically. The lighter weight lowers the inertia, enabling their incorporation without degrading the response of servo motors. Basic Specifications Brake torque : 5 N･m to 55 N･m Outer diameter of brake : 83.5 mm to 185 mm Operating temperature : -10℃ to 40℃

BXL Models

These are dry, spring-actuated brakes that are compact and dedicated for braking. They use a friction material with high wear resistance, stand up to long hours of use, have small torque fluctuations, and brake loads instantly even under abnormal circumstances.The effect of the rotor spring located on the outer periphery of the rotor reduces unpleasant high-frequency friction noise that occurs during braking. Braking is quiet. Basic Specifications Brake torque: 2 N･m to 22 N･m Operating temperature : 83 mm to 158 mm Backlash : -10℃ to 40℃

BXH Models

These are dry, spring-actuated brakes that are compact and dedicated for holding and emergency braking.They provide double the brake torque of BXL models of the same size. They naturally satisfy 100% of the rated torque values from the initial use, so the customer does not need to break them in. Basic Specifications Brake torque: 4 N･m to 44 N･m Operating temperature : 83 mm to 158 mm Backlash : -10℃ to 40℃
