What Is a Switchgear
What Is a Switchgear
Switchgear is a term that describes circuit breakers and electrical disconnect switches which are joined together to control and isolate electrical equipment. This merge clears any faults found downstream in an electricity distribution network and also turns on or off the power

Single-phase loads
Single-phase loads
Single-phase loads may be connected to a three-phase system, either by connecting across two live conductors (a phase-to-phase connection), or by connecting between a phase conductor and the system neutral, which is either connected to the center of the Y (star) secondary winding of the supply transformer, or is connected to the center of one winding of a delta transformer (Highleg Delta system) (see transformer and Split phase). Single-phase loads should be distributed evenly between the phases of the three-phase system for efficient use of the supply transformer and supply conductors

Synchro
سنکرو ها وسایلی هستند که می توانند جابجایی را در دو نقطه مختلف بدون استفاده از ارتباط مکانیکی و با استفاده از سیگنال های الکتریکی منتقل کنند
A synchro or "selsyn" is a type of rotary electrical transformer that is used for measuring the angle of a rotating machine such as an antenna platform. In its general physical construction, it is much like an electric motor (See below.)

DRIVING STEPPER MOTORS WITH THE L293D
Stepper motors are great to use in robotics. By energizing the coils in the motor in a particular sequence, a motor takes 48 or more small, precise steps to make one full revolution. If you are using two of these motors to drive your robot’s wheels, you can get good control over how far it travels by making the motors travel x many steps forwards or backwards

Three-phase electric power
Three-phase electric power is a common method of alternating-current electric power transmission.[1] It is a type of polyphase system mainly used to power large motors and other such devices. A three-phase system is generally more economical than others because

AC motor
An AC motor is an electric motor that is driven by an alternating current. It consists of two basic parts, an outside stationary stator having coils supplied with AC current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field

Electric Drive Basic Topology
The motor used in an electric drive is either a direct current (DC) motor or an alternating current (AC) motor. The type of motor used defines the electric drive's classification into DC motor drives and AC motor drives. The ease of producing a variable DC voltage source for a wide range of speed control made the DC motor drive the favorite electric drive up to the 1960s
