This manual introduces the solid state AC motor control installation and operation of Motortronics 10 to 1000 Amp Models Electronic Motor Brake Series. This manual includes information about the product theory, application, installation, wiring, and adjustment.
The Motortronics ABC Series is a solid state DC injection brake designed to stop three-phase AC induction motors by creating a stationary magnetic field in the stator windings. It features a built-in microprocessor for digital timing control, jogging, and braking, along with an integral Operator Interface Module for LED status indication and adjustments. The unit is suitable for applications where coast-to-stop times are undesirable, offering smooth, low peak level braking for quiet and steady operation.
| Motor Type | three phase AC induction motors |

| Brake Type | solid state DC injection brake |
| Maximum Brake Time Setting | 127 seconds |
| Brake Current Control | adjustable via Brake Current Potentiometer |
It is a solid state DC injection brake designed to stop three-phase AC induction motors by creating a stationary magnetic field.
It applies DC current to the starter terminals after the motor starter is turned off, creating a stationary magnetic field that pulls the rotor into alignment.
A mechanical brake must be used in conjunction with the ABC Series if emergency stopping is required where the stopping time must be shorter than the across-the-line start time.
