Delphi ATDC, AT24 and ATTD series self-braking motors use one 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 normally considered options by other brands, like:

  • The standard hand lever permits to release the brake, making it possible to move manually the shaft,
  • The PTO thermal protectors in the winding are a standard up to size 132. PTC are a standard from size 160 and up
  • Easy separate connection of the brake in case that the motor is connected to an inverter.

On ATDC and ATTD, the separate brake power supply is achieved, whenever needed, by connecting directly to the brake terminal board located inside the motor terminal box. On AT24 and ATTD24, the 24Vdc single or double brakes are designed to be directly connected to an inverter (usually having a 24Vdc plug)

On request, the brakes can be modified to be extremely silent for usage in special environments like theatres

 

Brake description

The delphi AT... series brakes are electro-magnetic brakes with negative operation, whose braking action is exercised in the absence of power supply
The brakes insulation class is 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 resined winding. The parts most subject to wear are treated in special atmospheres that provide considerable wear resistance to the parts.
