Discover the principles of proper motor switch selection, minimizing the risk of failure and optimizing machine operation

In industry, where process optimization and energy saving are crucial, the ability to smoothly change motor speed becomes an invaluable advantage. This article discusses the most popular methods of induction motor speed control, their advantages, and disadvantages.

In time of rising labor and spare parts costs, proper protection of electric motors is becoming crucial. Motor failure is not only a costly repair or replacement, but also production downtime, which can generate much greater losses. Therefore, the proper choice of protection and implementation of protection methods are absolutely fundamental.

Three-phase motors are widely used in industry because of their reliability, efficiency, and relatively simple design. Properly connecting such a motor to a circuit breaker and understanding how to change its direction of rotation is essential for engineers and technicians involved in maintenance and electrical installations. This article takes a step-by-step approach to these processes.

In world of industrial electrical engineering, the efficiency and reliability of drive systems are crucial. Start-up of induction motors, especially high-power ones, requires limiting of starting currents that can negatively affect the supply network and the motor itself. One of popular and proven solution is the use of a star-delta 0-Y-Δ system, which requires appropriately […]

Direct starter or Direct on-line (DOL) is the simplest form of motor starter. This method starting cage motors, the motor is connected using a starter across the full supply voltage. Depending upon size and design, motor might takes a low-power starting current about 5 to 7 times its full-load current. In normal conditions such currents […]
