Resistors for Motor Control

Resistors for Motor Control

Motor control resistors of any type for any application, including wound-rotor AC motors with slip ring starters, DC motor starters, crane control systems, torque-increasing resistors, field discharge resistors can be designed and built. Electric motors of all types AC single-phase or three-phase and DC have two common characteristics during starting and run-up. Without some form of control, the motor will take very high currents, and the switching may itself cause voltage spikes. The high currents risk overloading the supply...

Through Hole Resistor: Radial lead and Axial Lead

Through Hole Resistor: Radial lead and Axial Lead

A questions that comes up from time to time is what does axial or radial leaded mean? This is calling out how the leads comes out of the component. Axial leaded components will have a lead or multiple leads coming out of each end of the component. Structurally, using a form of carbon powder mixed with an insulating material, which does not conduct electricity at all, forms most through hole resistors. This is mixed with a paste or resin to create a solid inner core of the resistor, the conductive path. The ultimate resistance...

The Standard Resistor Colour Code Chart and Value Calculation

The Standard Resistor Colour Code Chart and Value Calculation

An international and universally accepted resistor colour code scheme was developed many years ago as a simple and quick way of identifying a resistors ohmic value no matter what its size or condition. It consists of a set of individual coloured rings or bands in spectral order representing each digit of the resistors value. The resistor colour code markings are always read one band at a time starting from the left to the right, with the larger width tolerance band oriented to the right side indicating its tolerance. By matc...

Resistors in Light Emitting Diode (LED) Circuits

Resistors in Light Emitting Diode (LED) Circuits

An LED (Light Emitting Diode) emits light when an electric current passes through it. The simplest circuit to power an LED is a voltage source with a resistor and an LED in series. Such a resistor is often called a ballast resistor. The ballast resistor is used to limit the current through the LED and to prevent that it burns. If the voltage source is equal to the voltage drop of the LED, no resistor is required. The resistance of the ballast resistor is easy to calculate with Ohms law and Kirchhoffs circuit laws. All LEDs re...

Standard EIA Decade Resistor Values Table

Standard EIA Decade Resistor Values Table

The Electronic Industries Association (EIA), and other authorities, specify standard values for resistors, sometimes referred to as the preferred value system. The preferred value system has its origins in the early years of the last century at a time when most resistors were carbon-graphite with relatively poor manufacturing tolerances. The rationale is simple - select values for components based on the tolerances with which they are able to be manufactured. Using 10% tolerance devices as an example, suppose that the first p...

How Does SMD Resistors Work with PCBs?

How Does SMD Resistors Work with PCBs?

SMD means Surface Mounted Device. An SMD is any electronic component that is made to use with Surface Mount Technology (SMT). SMT was developed to meet the ongoing desire for printed circuit board manufacture to use smaller components and be faster, more efficient, and cheaper. SMD resistors are divided into different packages. The term package refers to the size, shape and/or lead configuration of an electronic component. For instance, an IC chip that is has leads in two rows down opposite sides of the chip is called a Dual ...
