Abstract
The utility model relates to a high efficiency electromagnetic brake of electromechanical products, comprising a brake assembly, a dust cover, friction disks, a shaft sleeve, a rotor, a stator assembly, a motor shaft, a transform rectifying device and an adjusting nut. The positive and negative poles of the transform rectifying device is connected with that of the stator assembly; the brake assembly, the dust cover, the shaft sleeve, the rotor and the stator assembly are arranged on the motor shaft in series; the friction disks are arranged at both sides of the rotor; the stator assembly is provided with the adjusting nut. The utility model can respectively supply different electric voltages according to needs for the electromagnetic brake in starting state or normal work state; the exciting power is controlled within 20W, and the interrupting time is controlled within 80ms; when starting, the high efficiency electromagnetic brake has high sucking resultant force; when working normally, the high efficiency electromagnetic brake can save electricity and control the temperature. The brake rotor is interchangeable, reduces the discard damage of the entire machine, increases service life and lowers cost.
Description
Technical field: the utility model relates to a kind of high-efficiency electromagnetic break of electronic product.
Background technique: at present, all there are a lot of shortcomings in the electromagnetic brake of domestic and imported, and it is low that the home equipment ubiquity validity, and some high-tech and high precision apparatus can not be used, and the service behaviour difference is damaged easily.It is excessive that imported product exists in the equipment running process electric current, shortcomings such as selling at exorbitant prices.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of high-efficiency electromagnetic break is provided, it and supporting the linking together of transformation rectifying device (patent No. ZL00251803), problem such as it is poor to have solved service behaviour, and the life-span is low.The purpose of this utility model is achieved in that the high-efficiency electromagnetic break is made of brake assembly, dust-proof cover, friction plate, axle sleeve, rotor, stator assembly, motor shaft, transformation rectifying device, adjusting nut.The both positive and negative polarity of transformation rectifying device is connected with the both positive and negative polarity of stator assembly, brake assembly, dust-proof cover, axle sleeve, rotor, stator assembly are installed on the motor shaft successively, friction plate is equipped with on the both sides of rotor, and rotor adopts nonmagnetic alloy material, and adjusting nut is arranged on the stator assembly.This product has adopted transformation rectifying device patented technology (patent No. ZL00251803) and electromagnetic brake is supporting links together, exciting power is the 1/3-1/4 of domestic like product, it can be by the different needs of starting and different periods of proper functioning, supply with different voltage respectively, make exciting power be not more than 20W, turn-off time 80ms, reduced operating current, saved electric energy, main is to have reduced the work temperature rise, has improved technical performance index, the adhesive ability has improved 1.5 times, pickup time is fast, has avoided the hard friction phenomenon, and can allow the bigger working clearance.The brake braking force square is adjustable, the working life that is equivalent to the 3-5 platform of domestic like product working life, reduced user's economic burden, brake rotor has commutativity, reduced the complete machine loss from spoilage, brought great convenience to the user, the electromagnetic brake that it is produced with German Lenze company is compared complete machine weight and has been reduced 6%, copper cash weight reduces 12%, has therefore reduced cost.By 60,000 calculating, can save 1.44 hundred million yuan of huge foreign exchanges every year.
