Electrical braking for reduced braking time
- High demand braking time application
- High inertia application
Dynamic braking is a technique for electrical motor braking. The mechanical energy is converted to heat or electrical energy in order to slow and stop the motion.
With conventional braking systems, when the servo amplifier output power shuts off, the motor acts as a generator and converts the kinetic energy of the rotating motor and load into electrical energy.
Elmo’s highly reliable servo drives are design to reduce the servo braking time and dissipate the return energy from the motor when power off, by shortening all motor phases (to ground) while the drive is in Disable Mode
The following graphs shows motor braking results time with and without a dynamic braking.

* MO =0 – Servo is off
With dynamic braking
