Structure composition of linear motor
The structure of linear motor includes three parts: stator, rotor and support wheel.In order to ensure a good electromagnetic coupling between the stator and the rotor within the travel range, the core lengths of the stator and the rotor are different.The stator can be made into short stator and long stator.The long stator structure is seldom used because of its high cost and running cost.Like the rotary motor, the stator core is made of silicon steel, with a slotted surface.Three - phase, two - phase or single - phase winding are embedded in the groove;Single-phase linear asynchronous motor can be made into cover pole type, also can be through capacitance phase shift.
In the linear motor, equivalent to the rotating motor stator, called primary;The equivalent of a rotatable electro motor, called a secondary one, the primary one is communicating, and the secondary one is moving along the primary one in a straight line under the action of the electromagnetic force.The beginning is going to be long, and it's going to be long, and it's going to be long, and it's not going to be long.
Linear motor stator
The static part of the dc motor is called the stator, which is equivalent to the rotating motor stator and is called the primary. The stator is composed of three parts: stator core, stator winding and frame.The main function of the stator is to generate a rotating magnetic field.The stator is fixed on the housing.
The motor that moves back and forth during linear motor operation is the rotor, which is supported between two magnetic rails by the guide rail system. The coil is compressed together with epoxy material.The motor includes coil winding, hall circuit board, thermostat (temperature sensor monitoring temperature) and electronic interface.The rotor is non-steel, meaning no suction and no interference between the magnetic rail and the thrust coil.The non-steel coil assembly has small inertia and allows very high acceleration.The coil is generally three-phase, brushless phase change.
