  2. DC injection braking - Wikipedia

    en.wikipedia.org/wiki/DC_injection_braking

    A DC injection brake system can be used as an alternative or addition to a friction brake system. 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.

  3. ECE Regulation 90 - Wikipedia

    en.wikipedia.org/wiki/ECE_Regulation_90

    For the tests the vehicle brake for which the replacement linings are designed is installed in an inertia dynamometer instrumented for continuous recording of rotative speed, brake torque, brake line pressure, number of rotations after brake application, braking time, and brake rotor temperature.

  4. Maximum brake torque - Wikipedia

    en.wikipedia.org/wiki/Maximum_brake_torque

    Maximum brake torque (MBT) is the use of optimal ignition timing to take advantage of an internal combustion engine's maximum power and efficiency. There is always an optimal spark timing for all operating conditions of an engine. MBT is ideal at wide-open throttle (WOT), but not desirable when the engine is at idle.

  5. Mean effective pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_effective_pressure

    Speed has dropped out of the equation, and the only variables are the torque and displacement volume. Since the range of maximum brake mean effective pressures for good engine designs is well established, we now have a displacement-independent measure of the torque-producing capacity of an engine design – a specific torque of sorts.

  6. Direct torque control - Wikipedia

    en.wikipedia.org/wiki/Direct_torque_control

    Direct torque control (DTC) is one method used in variable-frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors.This involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor.

  7. Braking unit - Wikipedia

    en.wikipedia.org/wiki/Braking_unit

    Braking unit also some times referred as Dynamic braking unit may refer to: DC injection braking unit, an electrical braking device for ac motors; Regenerative braking unit, regenerative braking systems used in traction motors; Electromagnetic brake, devices using electromagnetic forces to mechanically brake

  9. Eddy current brake - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_brake

    Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...
