The Stator's role in a jet engine is to increase air pressure and help improve the direction and stability of the air flow. The stator, usually located in the compressor part of the engine, is a ring structure consisting of a series of stationary blades. Here's a detailed explanation of how stators increase air pressure in jet engines:Working principle What the compressor blades do: In a jet engine, the rotor blades rotate to compress the air entering the engine, thereby increasing the pressure

Gear pump is a pump that relies on one or more pairs of meshing gears to rotate to transport fluid. Gear pumps are usually used to transport viscous fluids, such as lubricating oil, hydraulic oil, polymer solutions, etc. As for whether the gear pump can drive a separate motor, this is actually a reverse problem, because normally, the motor drives the gear pump, rather than the gear pump drives the motor. Let's explore in detail:Working principle of gear pumpGear pump is mainly composed of a pair

Squirrel-cage induction motors (also known as squirrel-cage motors) are one of the most commonly used motor types in industry. When starting up, the characteristics of the squirrel cage motor are mainly determined by its starting current and starting torque.Starting currentStarting current refers to the current flowing through the motor when the motor is just switched on and starts to rotate. Since the speed of the motor is zero at this time, there is no back EMF generated, so the starting curre

Creepage in squirrel cage motors refers to the phenomenon where the rotor begins to rotate even though the motor is not receiving sufficient voltage to fully start or maintain rotation. This can happen under certain conditions, particularly when there is residual magnetism or when the motor is subjected to external forces that cause it to turn slightly. Here are the main causes of creepage in squirrel cage motors:Residual Magnetism Magnetic Fields: Even after the power supply is cut off, some re

The slip ring and brush in the induction motor are mainly used in the winding rotor induction motor, rather than the cage induction motor. In the winding rotor induction motor, the use and function of the slip ring and brush mainly include the following aspects:Slip ringThe slip ring is a metal ring fixed to the motor shaft, usually made of copper. The number of slip rings depends on the design of the motor and is generally the same as the number of phases in the rotor windings. The main functio

There is a close relationship between the rotor resistance of induction motor and its starting torque. Starting torque refers to the torque generated when the motor is started in a static state, which is an important indicator to measure the starting performance of the motor. The following is a detailed explanation of the relationship between rotor resistance and starting torque:Equivalent circuit model at startupIn order to understand the effect of rotor resistance on starting torque, it is fir

What is the Operating Principle of DC Motor?DC Motor DefinitionA DC motor is defined as a device that converts direct electrical energy into mechanical energy using magnetic fields and electrical currents.DC motors play a crucial role in modern industry. Understanding the working principle of a DC motor, which we explore in this article, begins with its fundamental single loop construction.The very basic construction of a DC motor contains a current carrying armature, connected to the supply end

What is the Torque Equation of DC Motor?Torque DefinitionTorque in a DC motor is defined as the force’s tendency to cause or change rotational motion.When a DC machine is loaded either as a motor or as a generator, the rotor conductors carry current. These conductors lie in the magnetic field of the air gap.Thus each conductor experiences a force. The conductors lie near the surface of the rotor at a common radius from its center. Hence torque is produced at the circumference of the rotor and ro
