Motor Control - Yaskawa

Variable Frequency Drives (VFDs) are electronic devices used to control the speed and torque of electric motors by varying the frequency and voltage of the supplied power. They are widely used in industrial and commercial applications to optimize energy consumption, improve motor control, and enhance system performance. VFDs enable precise speed control, soft starting, and acceleration, reducing mechanical stress and energy waste. They provide flexibility in adjusting motor speed to match specific process requirements, resulting in energy savings and increased efficiency. With features like built-in protection, advanced control algorithms, and communication capabilities, VFDs offer reliable and efficient motor control solutions for various applications.

Line reactors and output filters protect variable frequency drives (VFDs) and connected motors by reducing harmonic distortion, voltage spikes, and electrical noise in industrial power systems. Line reactors are installed on the input side to improve power quality and extend drive life, while output filters condition the waveform on the motor side to prevent insulation damage and overheating. Together, they enhance system reliability, reduce downtime, and ensure smooth, efficient motor operation in demanding environments.

Motor control parts are used to manage and regulate the operation of electric motors in various industrial and commercial applications. They include devices such as contactors, relays, motor starters, and variable frequency drives (VFDs), which control motor speed, direction, and protection. These parts are for smooth motor operation, energy efficiency, and safety in machinery, HVAC systems, and automation equipment.

Braking resistors and regenerative converters manage excess energy generated during motor deceleration in industrial drive systems, preventing overvoltage faults and improving system stability. Braking resistors dissipate surplus energy as heat in high-inertia applications, while regenerative converters feed that energy back into the power grid for improved efficiency and energy savings.

EMC filters, or electromagnetic compatibility filters, suppress conducted electrical noise and reduce electromagnetic interference (EMI) in industrial power systems, ensuring compliance with regulatory standards and protecting sensitive equipment. Installed at the input of drives, power supplies, and control panels, these filters improve signal integrity, prevent malfunction, and enhance overall system reliability in environments with high electrical noise. Essential for maintaining stable operation in automated and mission-critical industrial applications, EMC filters are a key component in modern electrical design.

Drive communication systems enable seamless data exchange between variable frequency drives (VFDs), PLCs, HMIs, and industrial control networks, supporting real-time monitoring, diagnostics, and precise motor control. Utilizing protocols like EtherNet/IP, Modbus, PROFINET, and DeviceNet, these interfaces integrate drives into complex automation architectures, improving system responsiveness, reducing downtime, and enabling predictive maintenance. Robust drive communication ensures interoperability and visibility across industrial environments demanding high-performance motion and process control.

Industrial phase converters enable reliable three-phase power from single-phase sources, allowing heavy-duty equipment like CNC machines, conveyors, compressors, and industrial pumps to operate in facilities without utility-supplied three-phase service. Engineered for high-performance, continuous-duty applications, these converters—available in rotary, digital, and static configurations—deliver balanced voltage, reduced harmonics, and efficient motor performance across demanding manufacturing and processing environments.
