Electronic Drives and Controls in Electromechanical Systems

Electronic drives and controls are essential components or systems utilized to regulate and manage the operation of electrical motors and other electromechanical devices. These systems play a pivotal role in controlling various parameters such as speed, torque, and direction of rotation, while also offering protection and monitoring functionalities.

Key Components and Functions:

  1. Control of Motor Parameters: Electronic drives and controls govern the operation of electrical motors by controlling parameters like speed, torque, and rotational direction. This enables precise adjustment and optimization of motor performance according to specific requirements.

  2. Interface Devices: These systems may include valve drivers and amplifiers, which facilitate communication and control between the electronic components and the electromechanical devices they regulate.

  3. Power Electronics Circuit: Electronic drives typically incorporate a power electronics circuit responsible for converting incoming electrical power into a suitable form for the motor. This conversion often involves adjusting voltage and frequency to meet the motor's operational needs.

  4. Feedback Sensors: Feedback sensors, such as encoders or other types of sensors, are employed to measure motor parameters accurately. This feedback information is utilized by the control system to adjust the power output, ensuring precise control over motor speed and position.

Integration with Programmable Logic Controllers (PLCs):

In addition to electronic drives, some hydraulic manufacturers offer programmable logic controllers (PLCs) that serve multiple functions. These PLCs not only power and control hydraulic products but also enable the integration of additional machine operations and sequences. By incorporating PLCs into their systems, manufacturers can enhance the flexibility, functionality, and automation capabilities of their electromechanical devices.


Electronic drives and controls are integral components in electromechanical systems, providing precise regulation and management of electrical motors and other devices. By leveraging advanced technologies such as power electronics circuits and feedback sensors, these systems ensure optimal performance, efficiency, and reliability in various industrial applications. Furthermore, the integration of PLCs expands the capabilities of hydraulic systems, enabling enhanced control and automation of machine operations.
