AC Inverter Drives and Systems
ACDC Drives stock a large range of AC drives to cover the vast spectrum of individual requirements. AC Inverter drives are used in many different applications, they vary considerably in complexity. The VFD's (variable frequency drives) are a powerful tool for energy saving, a cost effective alternative to running the AC motor D.O.L (Direct on line). AC Motor Control has transformed the way we operate our AC motors, they increase the motor life, increase service intervals, whilst cutting down energy consumption. Torque can also be limited which can help protect equipment by allowing it to operate within manufacturer tolerances, therefore extending its life.
We stock Parker, TECDrive and Yaskawa Inverters, and can offer technical support for all of the brands offered. We only stock the drives we personally use in the system solutions and service side of our company.
If you require assistance with retro fitting a newer drive to replace an older obsolete model, please call us on 01905 887 667 and we will happily help you to select a compatible equivalent. We also sell Accessories and add on Modules such as I/O communication cards, encoder cards and Dynamic Brake Resistors.
TECDrive AC inverters are a recent addition to the growing TEC range. Offering simple setup, along with multiple built in macros, they offer great value.
The Lenze range of AC inverters are frequently used on conyeyor systems or production lines. They have multiple safety features, such as 'Safe Torque Off' modules and interlocking.
Parker offer industry leading AC Inverters. With high end features such as Sensorless Vector and Microstepping included as standard even in the AC10 range, making for a feature rich and cost effective range.
Yaskawa are the largest manufacturer of AC inverters in the world. They offer class leading reliability and superb features, all in a compact package.
What Advantages do AC Inverters Offer?
AC inverters offer many benefits. Most motors in industrial applications are specced to allow for headroom, meaning they are oversized. These motors very rarely run at full load, so waste energy can be significant. Using an Inverter in such systems, can lead to large cost savings, either when retro fitting a drive to the exisitng system, or by not having to oversize the motor and system in the first place when designing new systems.
Inverters also allow for the control of starting currents, reducing the initial 'shock' on your motor, and increasing the longevity of the motor. Acceleration and decceleration can also be controlled, reducing bearing wear, and increasing the intervals between belt replacement when used with pulleys. Torque can also be limited, preventing unwanted damage to machinery.

Encoders - Closed Loop
A motor encoder is a rotary encoder mounted to an electric motor that provides closed loop feedback signals by tracking the speed and/or position of a motor shaft.
Encoders turn mechanical motion into an electrical signal that is used by the control system to monitor specific parameters of the application and make adjustments if necessary to maintain the machine operating as desired. The parameters monitored are determined by the type of application and can include speed, distance, RPM, position among others. Applications that utilize encoders or other sensors to control specific parameters are often referred to as closed-loop feedback or closed-loop control systems.
Why Buy from ACDC Drives?
We keep all inverters up to 55kW on the shelf, so if you need it next day it is no problem! We all know that in the modern workplace often things are needed as fast as possible. That is where we can help. We can also get enigineers out to site, to carry out surveys, or to install and commission drives on existing or new applications.
