Yaskawa Electric Inverters
Posted September 3, 2010 – 9:02 pm in: EquipmentThe average person would not be familiar with the phrase Yaskawa Electric Corporation before now but it’s most likely that they own something which, while being created, used at least one of the many products made by this company or, at the very least utilised an item which includes their technology. Yaskawa products are frequently used in various trades in different ways, for example in lifting, packaging and handling. Other areas of use include the areas of textiles, semiconductors, machine tools/woodworking, cranes & hoists, food & beverages, lifts & escalators, HVAC/fans & pumps and the manufacture of cars and other motor vehicles. Inverters are the most popular product range the company has.
The corporation produce a varied range of inverters both those optimised for applications and also those for general purposes. The company’s range of inverters include; the V1000, A1000, J1000, G7, L7, E7 and L1000 inverter drive. The company has factories in Japan and in many other countries and in 1998 they established their European facility in Cumbernauld, Scotland.
The J1000
The J1000 inverter is a highly cost effective inverter for general purposes. The drive features open loop vector control using the very latest technology. This superb motor control technology ensures both increased flexibility and greater performance. The J1000 inverter drive is available in both single and three phase with outputs starting at 0.2kW and going up to 5.5kW.
The V1000
The V1000 inverter is a further inverter for general purposes also featuring open loop vector control utilising the most recently developed motor control technology with the same benefits as the J1000 inverter drive above. With exceptional reliability and outstanding speed control the V1000 is available in both three and single phase with outputs starting at 0.18kW and going up to 18.5kW.
The A1000
The A1000 inverter is available in both three and single phase with outputs ranging from 0.75kW to 90kW.
The E7 Inverter drive
The E7 is suitable for use in fans and pumps. The E7 inverter islow noise and is optimised for HVAC functionality. The inverter drive is available in single phase and three phase with outputs from 0.55kW to 300kW.
The G7
The G7 inverter is immensely popular general purpose drive. using 3 level this drive vastly reduces hiccups relating to long cable runs. The inverter is available in three phase and single phase with outputs from 0.4kW to 300kW.
The L1000 and L7 Inverters
The L1000 and L7 inverter drives are exclusively lift inverter drives with many features. They are only available in three phase supplies with outputs from 4kW to 110kW.
If you wish to learn more about Yaskawa inverter drives you will need to contact Yaskawa themselves themselves alternatively you could contact a distributor who might be more willing to help you. In Britain one of the most respected distributors of Yaskawa inverter drives is Goodwin Electronics.

Posted September 3, 2010 – 9:02 pm in: EquipmentIn the world today we seem to be addicted to gadgets and those addicted are getting younger. In the consumer economy having ownership of the latest product is a badge of status. One aspect of technology which is becoming part of consumer products is components more commonly associated with robotics. Even though industrial robots are still very expensive consumer robotics are becoming less costly and correspondingly the relative components follow the same pattern. However some components of robotics are still costly and folk becoming involved in robotics as a hobby has to be careful and learn as much as possible in order to avoid expensive errors. One component often associated with robotics are servo motors but what are they?
Trying to find information about servo motors and drives online can be difficult and even if you find it the language is often over complicated and difficult to comprehend. Commonly the information is more relevant to industrial situations. This is often the case in the field of motion control and servo motors and drives.
Servo motors are vital elements in robotics but are also components used in such gadgets as radio controlled cars and radio controlled airplanes. Servos are small devices which feature a shaft (a rod or pole which is able to be placed at specific angles by using a coded signal. By changing the signal the servo will accordingly alter the angle of the shaft.
Although Servo motors are relatively small they have incorporated control circuitry and they are incredibly powerful packing enormous torque. All of this power is controlled by just three wires, one for earth and the other 2 for power and control.
The Complicated Part
Sadly it is unavoidable and I have to be a little technical here, but try to stay with me and you may discover that you understand the concepts.
As well as the control circuit servos feature a component called a potentiometer (a variable resistor) which is connected to the shaft. The potentiometer assists the control circuit to measure the current angle of the servo.
Normal servo motors control angular motion up to 180 degrees, a small number of servos go further however to exceed two hundred and ten degrees is near impossible and they have a mechanical stop which is built into the main system to prevent this.
The Servo Drive
Servo drives are used to power electric servos. By changing the current sent to the servo the drive enables proportional control. As the level of power sent to the servo motor is proportional to the amount of distance it travels extremely accurate movement is possible.
Servo motors are utilised in many areas of industry such as CNC machining, factory automation and robotics. While these Servo motors are commonly huge they can also be much smaller for using in various consumer products and hobby systems such as the popular Lego Mindstorms.
If you need to discover more about, or need buy industrial servo motors you really need to contact a specialist such as Goodwin Electronics in the British Isles.
