Press Release Summary:
Measuring 7 x 5 x 6 in., EMB-300CP employs series of springs that apply force to friction disc and are released when voltage/current is applied. Brake can produce 710 lb axial force and is made to operate with disc thickness of 12.5 mm. Requiring 2-wire hook up, product has normal operating voltage of 45 V but supports excitation to 90 V for accelerated response. For increased torque, modular design enables multiple brakes to be added to single disc.
Original Press Release:
New Spring Applied Electric Caliper Disc Brake
Most caliper disc brakes currently available are either controlled pneumatically or hydraulically. The new spring applied electric caliper disc brake (EMB-300CP) from Ogura uses a series of springs to apply force to a friction disc and is released when voltage/current is applied. Since this brake operates electrically and only needs a simple two wire hook up, installation costs are far less than pneumatic and hydraulic brakes which require supply lines and compressed air or hydraulic fluid. The brake is approximately 7 inches in length, 5 inches in width and 6 inches in height. It can produce 710 lbs. of axial force and is made to operate with a disc thickness of 12.5 mm. Normal operating voltage is 45 volts but typically over excitation is used to get a quick response, so the brake is made to operate with an over excitation of 90 volts.
Since the brakes are modular in design, multiple brakes can be added to a single disc to increase the torque. If two brakes are used on one disc, the torque doubles.. Customers also have the option, if space is available, to increase the size of the disc to increase the torque. For example, the torque from an 8" disc would be about 150 lb. ft. and from a 16" disc, it would be 300 lb. ft. Brakes can also be made with integral limit switches so that a system would register if the brake is either engaged or disengaged. All brakes also come with manual release nuts so brakes can be released in an emergency. Although, mainly designed for hoist and elevator applications, these low cost modular brakes can be used in a variety of industrial applications.
Theses brakes are only a small part of over 3,000 different clutch and brake models that Ogura has available.
