DELPHI AT self-braking motors

selfbraking motors use one or 2 spring-pressure brakes

Delphi ATDC, AT24, ATTD and ATTD24 series selfbraking 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 he 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 electromagnetic 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.
