Drive control system and components

The drive control system is essential for the precise operation of industrial electric motors. It is crucial in controlling speed, torque and direction, ensuring optimum motor performance.

Servo drive

The servo drive is a motion control system that ensures high position accuracy. This is very important in industries such as mechanical engineering, robotics, CNC machines and automated production lines, where precision and responsiveness play a key role. By integrating intelligent control algorithms, the servo drive ensures stable operation and promotes efficiency, thus playing an indispensable role in industries with high demands on precision.

Variable Frequency Drives

A variable frequency drive is a component of an electric motor control system. It allows the speed of the motor to be controlled by adjusting the frequency and voltage supplied to the motor. The variable frequency drive helps to reduce power consumption, improve process control and extend the life of electric motors. Variable frequency drives are very common and can be found in all sectors, from HVAC systems to conveyor belts, they help to optimise energy efficiency while maintaining flexibility, thus allowing adaptation to changing operational requirements.


In cases where rapid acceleration can cause mechanical shock or voltage fluctuations, the use of soft starters is particularly important. Soft starters gradually increase the speed of the motor, minimising mechanical shock and reducing the impact on the power supply. This not only protects the equipment but also extends the life of the electric motor. Softstarters, commonly used in pumps, fans and compressors, provide soft starting, reducing wear and tear associated with rapid motor start-up.

Star - Delta starters

The star-delta starter is indispensable when using high-power asynchronous motors. This starter initially connects the motor in a star configuration, reducing the starting current and minimising voltage drops. When the motor reaches a certain speed, it switches to the delta or triangle configuration to ensure efficient operation at full load. This starting method is particularly effective in minimising electrical disturbances during the critical start-up phase and ensuring a smooth transition to full operation.

DC brakes

When rapid deceleration or torque retention is needed, a DC brake is the right solution. These brakes are often used on hoists, cranes and conveyors where DC is used to generate braking torque. DC brakes provide precise control of the braking force, improving safety and preventing unintended movement. Their robust design and fast response make them an indispensable component where rapid and controlled deceleration is critical.

Electric motors

At the heart of every drive control system is an electric motor. Whether AC or DC, it converts electricity into mechanical motion. Advances in motor technology, such as brushless technology and the development of high-efficiency designs, contribute to the overall efficiency and performance of drive systems. However, to optimise energy consumption and ensure long-term performance, it is important to choose the right electric motor for the job.

Position actuators

If precise position control is important, then position actuators are the components that provide the necessary functionality. Using encoders or sensors, position actuators receive precise information from the drive control system, guaranteeing that the electric motor maintains the desired position. This technology is vital in industries such as robotics, CNC machining and automated assembly lines, where precise positioning is critical to the success of the process.
