Motors used in industrial facilities and large-scale infrastructure projects are essential for ensuring efficient and reliable system operation. The correct starting and stopping of Low Voltage (LV) and Medium Voltage (MV) motors not only extends the lifespan of the motors but also increases energy efficiency. At Maytek Energy, we assist our customers in managing their motors safely and efficiently through the innovative and reliable solutions we offer in LV and MV motor starting systems.

What Are LV and MV Motor Starting Systems?

Motor starting systems are systems that control and manage the excessive current and voltage fluctuations that can occur when electric motors are first started. These systems ensure that the motor is gradually brought into operation, preventing damage to the motor and connected systems.  LV motors generally operate below 1 kV, while MV motors operate between 1 kV and 36 kV. Correct motor starting methods are crucial for both energy efficiency and system safety.

Types of Motor Starting Systems:

• Direct On-Line Starting (DOL): The motor is connected directly to the grid at full voltage. This method is commonly used for small motors.
• Star-Delta Starting: This method starts the motor at a lower voltage and then switches to full voltage after a set period. It is suitable for large motors.
• Autotransformer Starting: A method that gradually increases the voltage level to start the motor. Similar to star-delta starting, it reduces the initial current drawn by the motor.
• Soft Starter: A device that gradually increases the voltage during startup, allowing the motor to slowly come online. It reduces stress on the motor.
• Variable Frequency Drive (VFD): A motor starting system that controls motor speed and torque, improving energy efficiency. With soft start functionality, it helps save energy and extend motor life.

Importance of Motor Starting Systems
The correct design and application of motor starting systems are critical for energy efficiency, motor longevity, and system safety. Incorrect starting methods can lead to excessive current, voltage fluctuations, and damage to equipment.

Main Advantages of Motor Starting Systems:

• Energy Efficiency: Correct motor starting systems optimize motor energy consumption and reduce operational costs. This is especially important for large motors to achieve energy savings.
• Extended Motor Life: Starting systems protect the motor from sudden voltage and current fluctuations, reducing wear and tear and extending the motor’s lifespan.
• System Safety: Starting systems protect other equipment and the grid from excessive current and sudden voltage changes, enhancing overall system safety.
• Reduced Maintenance Needs: Motors and other electrical equipment experience less wear and tear with proper starting systems, reducing maintenance needs and costs.
• Compatibility and Flexibility: Starting systems provide adaptable solutions for different motor types and load conditions, making it easier to integrate into various industrial applications.
