Self braking motors with 1 or 2 spring-pressure brakes
IE2, high efficiency class IE 60034-30IE3, premium efficiency class IE 60034-30Delphi ATDC, AT24, ATTD and ATTD24 series
self braking motors
use 1 or 2 spring-pressure brakes, firmly spliced onto a cast iron shield at the back of the motor.
These motors include a series of characteristics:
Brake description The Delphi AT... series brakes are electromagnetic brakes with negative operation, whose braking action is exercised in the absence of power supply.
The brakes are insulation class F.
The brakes lining is asbestos-free.
The rectifier is of relays type, with protection varistors at the entry and the exit.
All brake assemblies are protected against corrosion by painting or heat galvanizing and resigned winding.
The parts most subject to wear are treated in special atmospheres that provide considerable wear resistance to the parts.
