Is a Modular Encoder Right for Your Application?

Modular, or "Kit", encoders are actually a specialized category of rotary encoders. The difference between a modular encoder and a standard encoder is that the modular encoder does not incorporate internal bearings into its design. Instead, it relies on the host, typically a motor, to supply the structural integrity necessary for proper operation. At first glance, this approach seems to be a good idea, since eliminating the bearings can lower the price of the encoder and give the overall encoder Read

What is an AC Drive?

AC Drives are also known as Inverters, Variable Speed Drives (VSDs), Variable Frequency Drives (VFDs) and Frequency Converters. AC Drives are used to control AC Induction motors; the most common motor technology used in industry. The motors are rugged, require very little maintenance and can easily be manufactured with high environmental protection. Read

How Does A VFD Inverter Work?

You can divide the world of electronic motor drives into two categories: AC and DC. A motor drive controls the speed, torque, direction and resulting horsepower of a motor. A DC drive typically controls a shunt wound DC motor, which has separate armature and field circuits. AC drives control AC induction motors, and-like their DC counterparts-control speed, torque, and horsepower. Read

Determining Sensor Response Speed

The response speed of a sensor is an important feature that one should consider when specifying a sensor for an application, especially if that application involves high speed movement like many of today's manufacturing processes. However, it's very easy to overestimate what you really need based a perceived notion that a process is "ultra-fast". Read

Understanding Modern Electrical Motors

Modern electrical motors are available in many different forms, such as Single Phase Motors, Three-Phase Motors, Brake Motors, Synchronous Motors, Asynchronous Motors, special customised motors, Two Speed Motors, three speed motors, and so on, all with their own performance and characteristics.
