Magnetic fieldProperty of space that quantifies the magnetic influence at a given locationIn magnetism and electromagnetism, magnetic field is a physical property of space that quantifies the magnetic influence at a given location.
Electric motorMachine that converts electrical energy into mechanical energyAn electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate Lorentz force in the form of torque applied on the motor's shaft.
Rotor (electric)The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis. Early developmentAn early example of electromagnetic rotation was the first rotary machine built by Ányos Jedlik with electromagnets and a commutator, in 1826-27.
Stator (electric machines)Electric machines function through the interaction between a rotating component, the rotor, and a non-rotating component, the stator. In an electric motor, the stator provides a magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. DesignMotor stators are made either from iron/steel or from a printed circuit board (PCB).
Lorentz forceIn electromagnetism, the Lorentz force is the force exerted on a charged particle by electric and magnetic fields. It determines how charged particles move in electromagnetic environments and underlies many physical phenomena, from the operation of electric motors and particle accelerators to the behavior of plasmas. The Lorentz force has two components.
Linear equationIn mathematics, a linear equation is an equation that may be put in the form a1x1+…+anxn+b=0,{\displaystyle a_{1}x_{1}+\ldots +a_{n}x_{n}+b=0,} where x1,…,xn{\displaystyle x_{1},\ldots ,x_{n}} are the variables (or unknowns), and b,a1,…,an{\displaystyle b,a_{1},\ldots ,a_{n}} are the coefficients, which are often real numbers.
Electric currentAn electric current is a flow of charged particles, such as electrons or ions, through an electrical conductor or space. It is defined as the net rate at which electric charge flows through a surface. The moving particles are called charge carriers, which may be of several types, depending on the conductor. In electric circuits, the charge carriers are often electrons moving through a wire. In semiconductors, the charge carriers can be electrons or holes.
Linear motionLinear motion, also called rectilinear motion, is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of two types: uniform linear motion, with constant velocity (zero acceleration); and non-uniform linear motion, with variable velocity (non-zero acceleration).
ForceInfluence that can change motion of an objectIn physics, a force is an action that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure in a fluid. In mechanics, force makes ideas like pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity (force vector).
TorqueIn physics and mechanics, torque is the rotational correspondent of linear force. It is also referred to as the moment of force, or simply the moment. Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen axis. For example, when driving a screw, a screwdriver applies torque to the screw, causing it to tend to rotate around its axis.
Computer numerical controlComputer numerical control (CNC) or CNC machining is the automated control of machine tools by a computer. It is an evolution of numerical control (NC), where machine tools are directly managed by data storage media such as punched cards or punched tape. Because CNC allows for easier programming, modification, and real-time adjustments, it has gradually replaced NC as computing costs declined.RotationRotation, also known as rotational motion or rotary motion, is the movement of an object that leaves at least one point unchanged. In 2 dimensions, a plane figure can rotate in either a clockwise or counterclockwise sense around a point called the center of rotation. In 3 dimensions, a solid figure rotates around an imaginary line called an axis of rotation.*As an Amazon Associate I earn from qualifying purchases.
