The use of braking systems is necessary to control various motors and machines. Correct and safe operation is a must when motors and the machines need to be slowed or stopped. In this post, we’ll be sharing our top three reasons for using electronic brakes. If you’re ready to request a quote or make a purchase, feel free to give us a call today!
The Reasons for Braking Systems
As you continue your research across the internet or with various experts, you’ll find many reasons why braking systems, whether electronic or mechanical, exist. We’ve decided to share our three main reasons why to use braking systems across all the applications and industries we service and support:
Speed Control: In most cases, electronic and mechanical braking is used to slow and stop a motor. However, when controlling speed in an induction motor, it’s important to be able to control speed for proper and efficient use.
Emergency Stop: In some cases, an emergency stop is necessary to retain or salvage the safety of those around the motor. Braking systems in any capacity are built primarily to ensure the safety of those operating or maintaining the motor.
Hold Control: When the motor is not in operation but still receiving current, it’s possible to keep it from engaging. Mechanical and electronic braking systems can keep a motor still for a period of time.
The Types of Electronic Braking Systems
Eddy Current: A separate current is coupled to the shaft of the induction motor to create magnetic fluxes that oppose the motor and produce opposing torque.
DC Injection: Direct current is applied to the AC induction motor to slow and stop the motor’s inertia.
Plugging: At the stator terminals of the AC induction motor, the voltage sequence is reversed to create an opposing force to stop the motor. The reversal of the polarity is the method of slowing the motor to a stop.
Heat dissipation is a concern when using electronic braking systems. However, if you know how the heat is dissipated, you can effectively manage it and the braking system to operate at peak performance. DC injection and plugging dissipate heat through the motor, and eddy currents dissipate heat through the conductor.
The Three Reasons To Use DC Injection Braking
Effectiveness: DC injection allows for a quick, smooth deceleration of the motor that is faster than if the motor was allowed to coast to a stop.
Safety: As an alternative to mechanical braking, DC injection allows for effective stopping of a motor without the hazards of friction braking.
Low-Maintenance: DC injection brakes do not wear like mechanical brakes because they do not use friction to slow or stop the motor, resulting in virtually no brake maintenance over time.
