What is a High-pass Filter?10 March 2021
A high-pass filter is a combination device of capacitors, inductances, and resistors that allow signal components above a certain frequency to pass, while greatly suppressing signal components below that frequency. The high-pass filter only attenuates the frequency components below a given frequency, and allows the frequency components above the cutoff frequency to pass, and there is no phase shift filtering process. Mainly used to eliminate low-frequency noise, also called low-cut filter.
What is a Servo Motor?09 March 2021
Servo motor refers to the engine that controls the operation of mechanical components in the servo system and is a motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately and can convert the voltage signal into torque and speed to drive the control object.
Introduction to Reluctance Motor08 March 2021
This is a kind of advanced motor that, like a regular electric motor, has both a stator and a rotor. This motors use a direct spinning magnetic field (RPM) to synchronize the rotor's speed with the stator's RMF. These motors offer a high power density at a low cost, making them appealing in a variety of applications. The reluctance motor's operating theory is that if a magnetic material is placed inside a magnetic field, it often pulls itself into line in the least reluctance manner.
What is Solid-state Battery08 March 2021
A solid-state battery is a battery that uses solid electrodes and solid electrolytes. Solid-state batteries generally have low power density and high energy density. Because of the relatively high power and weight of solid-state batteries, it is an ideal battery for electric vehicles.
Nickel-Cadmium Battery: Construction, Features and Working Principle06 March 2021
A nickel-cadmium battery is a system that generates DC voltage by a chemical reaction between the components. In a nickel-cadmium battery, the redox material serves as the nucleus, with a nickel sheet and a separator surrounding it. The voltage of the nickel-cadmium cell is about 1.2 V. As three or four cells are connected in sequence, the output voltage ranges from 3.6 to 4.8 V.
What is a Motor Starter?06 March 2021
A motor starter is an electrical system used to safely start and stop a motor. Like a relay, the motor starter turns power on/off, which offers low voltage and overcurrent safety, as opposed to a relay.
Introduction to AC motor05 March 2021
The motor which uses an electromagnetic induction phänomen to convert the alternative current into mechanical power is called an AC motor. An alternating current drives this motor. Two main components of the AC motors include the stator and the rotor. The stator is the motor's permanent component, and the rotor is the revolving part of the motor. The AC motor can be single or 3-phase.
Introduction to Lead Acid Battery: Construction, Working Principle and Types04 March 2021
The rechargeable and secondary batteries category includes lead acid batteries. Despite the battery's low energy-to-volume and energy-to-weight ratios, it can deliver higher surge currents. This refers to the fact that lead acid cells have a high power-to-weight ratio.
Structure, Types and Working of Dry Cell04 March 2021
A dry cell is an electrical power generator dependent on chemical reactions. The cell pushes the electrons to fluid from one end to the other when the two electrodes are bound in a closed way. The electron flow allows the electrons to flow into the closed system.
What is a Lithium-ion Battery?03 March 2021
Lithium-ion or lithium polymer type is the most frequent type of rechargeable battery in consumer electronics. In this post, we'd be interested in the Li-ion battery because it's more useful than any other kind. Whether it's a small power bank or laptop or just as wide as the latest model 3 of Tesla, it's all powered by a lithium-ion battery.
Stepper Motor: Types, Working and Applications02 March 2021
A brushless, synchronous electric motor that converts digital pulses to mechanical shaft rotation is known as a stepper motor. When operated by a sequentially switched DC power supply, the normal shaft motion is made up of discrete angular motions of approximately uniform magnitude.
Linear Induction Motor: Working Principle, Characteristics, and Applications02 March 2021
LIM stands for Linear Induction Motor, and it is an improved version of the rotary induction motor that produces linear translational motion instead of rotating motion. Other than rotating torque, this device generates linear movement and force. By cutting a radically shaped cut in the revolving induction and thus leveling the section, the design and functionality of the linear induction motor can be demonstrated in the diagram below.
