  2. DC injection braking - Wikipedia

    en.wikipedia.org/wiki/DC_injection_braking

    DC injection brakes only require a small module located with the other motor switchgear and/or drivers, mounted in a remote and convenient location, whereas a friction brake must be mounted somewhere on the rotating system. Friction brakes eventually wear out with use and require replacement of braking components. DC brake modules do not have ...

    In 1985, Rockwell International purchased Allen-Bradley for $1.651 billion; this was the largest acquisition in Wisconsin's history to date. [3] For all intents and purposes, Allen-Bradley took over Rockwell's industrial automation division. The 1990s featured continued technology development, including the company's launch of its software ...

  6. Brake-by-wire - Wikipedia

    en.wikipedia.org/wiki/Brake-by-wire

    The controller provides drive control commands for a power control module. This module controls three phase drive currents for the brake actuator which is a permanent magnet DC motor, energised by 42 V sources. In addition to tracking its reference brake command, the caliper controller also controls the position and speed of the brake actuator.

  7. Braking chopper - Wikipedia

    en.wikipedia.org/wiki/Braking_chopper

    A braking chopper is an magnetical switch that limits the DC bus voltage by switching the braking energy to a resistor where the braking energy is converted to heat. Braking choppers are automatically activated when the actual DC bus voltage exceeds a specified level depending on the nominal voltage of the variable-frequency drive
