Yaskawa VFDs

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).

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. 

Variable Frequency Drives (VFDs)

Variable Frequency Drives (VFDs) allow for the slow ramp up of a motor during startup and the slowing down of the motor during shutdown. They also allow 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.
