This document provides information about Motortronics products, including the theory of operation, brake sizing and selection, and applications. The document also includes guidelines for installation, wiring, adjustments, and start-up of the product.
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 and an integral Operator Interface Module with LED status indication. The device allows for smooth, low peak level braking suitable for high inertia loads.
| Motor Type | three-phase AC induction motors |
|---|---|
| Brake Design | full-wave DC brake design |
| Maximum Brake Time Setting | 127 seconds |
No, all DC injection brakes inherently lose braking torque when the motor stops and cannot be used as holding brakes.
The maximum brake time setting is 127 seconds.
No, DC injection brakes cannot be used for holding a load after it comes to a stop.
If power is lost, no braking will take place.
