What is the engine driver?

The term motor driver describes a group of electronic and electromechanical equipment used to start and operate electric motors in a pre -defined manner. They can be used to gradually increase the speed of the engine at startup, increase the initial torque, or reverse the rotary direction of the engine. These control phases are usually necessary due to the requirements of the surgical environment, specific installation requirements or to increase the efficiency of the engine. The motor driver can be slightly more than just a relatively simple operator interface, such as direct online starter or highly sophisticated and automated soft starter or frequency drive.

Electric motors form the backbone of most industrial and production environments and in most similar installations can be found in large numbers. If it comes with a suitable electric current, the engine begins, accelerates to the maximum speed of the construction and continue running until the power supply is supplied. I will slow down the buds then I slow down until the inertial forces run outThey do the pulse of the rotor and the engine stops. In the simplest installations, the introduction and stopping of the energy is all necessary control, and if the correct engine size is used, the system will operate correctly with more than a simple starting and stop station. Unfortunately, most large, complex installations require a much more sophisticated control over many of their machine units.

Many machines require a gradual increase in rotary speed during startup mode. Other high -load machines, such as underground ventilation fans that have a fan weighing many tons, also require gradual initial speeds to overcome considerable inertia of static blade to prevent motor trips and mechanical damage. Other installations require one engine to reverse the rotary dirction at will or be capable of speed range during normalHo to operate.

All these operating requirements can be achieved using one of the wide range of available motor controllers. These devices fall into two basic categories: electronic and electromechanical controllers. Electronic units of engine motor control are generally very sophisticated and include categories of devices such as soft starting and variable frequency units that can gradually increase the speeds of initial and control speed. They can also be programmed to respond to a wide range of system inputs or preset operating conditions.

Electromechanical motor driver is simpler of these two groups and generally uses electromagnetic contactors or relays to stop, start and reverse the direction of the engine. In the case of three -phase Star/Delta starters, they can also be used to overcome the high initial load by running the engine in a high -torque configuration configuration. Once I am initiallyThe innerial load is overcome, then switches to a more economical and efficient Delta with low torque delta. In some older speed control systems, mechanical variable resistance is used to control the engine speed.
