Safety requirements for electrical part of the brake（一）

         Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. We can supply a full-range of power transmission products, such as chains, Transmission Chain,Stainless Steel Chain,sprockets and plate wheels, pulleys, gearboxes, motors, Elastomer Coupling, gears and racks. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, torque limiters, shaft collars, motor bases and motor slides, chain detachers, Timing Belt Pulleys,chain guides, universal joint, rod ends and yokes. Our products are used in many different industry sector, like in automation engineering, drive engineering, conveyor technology, assembly and handling technology, packaging industries, the beverage, food and medical engineering, pharmaceutical production, and laboratory equipment.

    Because the brake is used in machine electricity type, so the test of the electrical part of the brake is also very important.

    1.In the working voltage, the traction machine operation mechanism, load sustained rate and cycle operation, when the brake to achieve thermal stability, measuring the brake coiltemperature rise. Method for measuring GB 755-2008 "rotary motor rating and performance" article 8.6.2 resistance measurement and calculation. 

    The insulation class B, brake coil temperature should not exceed 80K; the insulation class F, brakecoil temperature should not exceed 105K. For the bare surface temperature of more than 6 (TC brake, should be increased toprevent scalding warning signs.

Electromagnetic Clutches And Brakes

    2.The coil voltage withstand test brake should meet theconductive part for lmin to 1000V applied voltage, between, should not appear the breakdown phenomenon.

    3.Should be raised minimum pull in voltage and the release voltage brake electromagnet test after the end of the brake temperature. GB/T 24478-2009 "elevator": brake electromagnetminimum pull in voltage and release voltage should be less thanthe highest rated voltage of 80% and 55%.
