Specific implementation mode：
As shown in Figures 1 to 5, a kind of DC electromagnetic brake includes electromagnet 1 with coil 23, fixed disk 4 and anti-
Dust hood 5, coil 23 are that one group of enamel-cover being fixed in 1 inner annular circular groove of electromagnet is poured by insulated paint with insulating frame
Line, the inner ring of electromagnet 1 are equipped with end cap 7, and fixed disk 4 is stationary friction pair part, which is provided with it is multiple to change
The bolt I10 of frequency motor connection is equipped with brake disc 3 between fixed disk 4 and electromagnet 1, and brake disc 3 is by stainless steel or aluminium alloy sheet
What body and the bonding of special friction material formed has great friction coefficient and low rate of wear, and can transmit the part of design torque, makes
The inner ring of Moving plate 3 is equipped with spline housing 6, and armature 2 is equipped between brake disc 3 and electromagnet 1, is equipped between armature 2 and electromagnet 1 more
