Delphi electric motors with autonomous brake ATDC, AT24, ATTD and ATTD24

The Solid Engineering company offers self-braking electric motors that use 1 or 2 spring brakes.

The ATDC, AT24, ATTD and ATTD24 self-braking Delphi electric motors use 1 or 2 spring brakes firmly attached to a cast iron screen at the rear of the motor.

These engines include a number of features that are usually seen as options in other brands, such as: A standard hand lever allows you to release the brake, which allows you to manually move the shaft. Thermal protection of PTO in the winding - standard up to size 132. PTC - standard from size 160 and above.

Simple separate connection of the brake in case the motor is connected to the converter.

In ATDC and ATTD, a separate brake power supply, if necessary, is connected directly to the brake terminal block located inside the motor terminal box. The AT24 and ATTD24 have single or dual 24 Vdc DC brakes for direct connection to the converter (usually with a 24 Vdc connector). The brakes can be modified to be very quiet for use in special environments such as theaters.

Brakes of the Delphi AT ... series are electromagnetic brakes with a negative action, the braking action of which is carried out in the absence of power supply.

Brake insulation class - F.

The brake pad does not contain asbestos.

Relay-type rectifier with protective varistors at the input and output.

All brake assemblies are protected from corrosion by painting or hot-dip galvanizing and resin coating.

The parts that are most prone to wear are processed in special atmospheres that provide significant wear resistance of the parts.

Many options and special versions, for example:

  - silent brake,

  - ultra-fast rectifier (switching time <50 ms),

  - microswitch on the brake,

  - rubber seal on the brake,

  - ATEX explosion-proof brake, etc.
