Yaskawa VFDs
Yaskawa Variable Frequency Drives (VFDs) that use advanced technology, high performance, and proven reliability make them a popular choice across many industries. They provide precise control over motor speed and torque that can improve not only energy efficiency but also process control—and even the life of the equipment itself. That's why they're used in applications like HVAC systems, pumps, conveyors, cranes, and machine tools.
Yaskawa variable frequency drives (VFDs) are used in many different types of applications because they can be programmed to work with a wide variety of motors and systems. Within the VFD, there are two primary technologies: vector control and flux vector control. Both do the same basic job, which is to regulate the smooth operation of an AC motor such that it produces a consistent speed and torque under all operating conditions.

More Information about Yaskawa VFDs
Yaskawa A1000
Yaskawa A1000 are full featured drives that provide performance and flexibility from simply fans and pumps to complex machines. The open or closed vector control allows for regulation, torque production and position control capability, while the continuous auto-tuning optimizes performance by compensating for changes in motor temperature. Fast-acting current and voltage limiters help achieve continuous drive operation during periods of excessive demand.
Yaskawa GA500
Yaskawa GA500 Microdrives are designed for 10 years of continuous operation and are able to run any induction, permanent magnet or synchronous reluctance motors. They can be programmed without any power supply connected by simply plugging into a PC'S USB port or any mobile USB device.
Yaskawa P1000
Yaskawa P1000 drives are an ideal choice for industrial fan and pump applications. They provide reliable, cost-effective control for variable torque loads through 1000 HP.
Yaskawa U1000 Industrial Matrix
Yaskawa U1000 Industrial Matrix drives provide excellent harmonic performance and regeneration in a single stand-alone drive solution without the need for additional components. Yaskawa's matrix technology creates a variable output by switching directly from the input power (AC to AC; no DC bus).
FAQs
Is the Z1000U Matrix Drive specifically designed to directly convert input AC voltage to output AC voltage as one of it's features?
Yes, the Yaskawa Z1000U Matrix Drive is specifically designed to directly convert input AC voltage to output AC voltage, providing efficient and seamless power conversion.
Motor Starters, Soft Starters and VFDs
Motor Starters
Motor starters safely start and stop a motor in industrial applications. They are designed with a contactor, overload and circuit protection. They are used when basic motor control is required, where torque on the motor is not a concern and speed control is not needed. The advantages of motor starters include: lower cost, allows for remote operation, allows for monitoring of motor state (with the use of auxiliary contacts) and they are safe and efficient. The disadvantages include: high inrush current that can cause fuses to blow and breakers to trip if the inrush is too high, and the starter will allow a full torque to start the motor which can cause the motor to ramp up to full speed very quickly potentially causing the motor to wear and degrade prematurely.
Soft Starters
Soft starters protect motors from inrush current by gently ramping up the motor to full speed. They provide all of the same functions as a traditional motor starter. The advantages of soft starters include: they are less expensive than a VFD when only startup control is needed, they are a smaller system than a VFD where space is a concern and they prevent unwanted torque upon startup, prolonging the life of the motor. The disadvantages include: they are more expensive than a traditional motor starter and they do not allow for full speed control.
VFDs
A Variable Frequency Drive (VFD) allows for the slow ramp up of a motor during startup and the slowing down of the motor during shutdown. It also allows for full speed control during the entire run cycle of the motor. VFDs provide the same functions as both the traditional motor starters and soft starters. The advantages of VFDs include: full speed control (start, stop and in-between), more custom control and monitoring, energy savings due to efficient motor usage and less wear and tear on the motors. The disadvantages include: they are more expensive and larger than other motor control options and they generate heat that may require fans or AC units.
