The structure and type selection of the internal drive linear motor. The result of this is that the design is greatly simplified, so that in many application fields, the linear stepping motor can be directly used to stop the fine linear motion without the external mechanical linkage device. External drive the structure of the linear motor and the selection of the structure of the external drive linear motor.
The structure of the external drive linear motor is compared with the selection of the linear stepper motor and the rotary motor. It can directly move linearly, which can make the machine compact and make the design simpler. The basic principle of the external drive linear motor is that the rotor of the external drive linear stepper motor is for permanent magnets, when current flows through the stator windings, the stator windings generate a vector magnetic field, which drives the rotor to rotate to a certain angle.
This makes the pair of magnetic field directions of the rotor diverge from the magnetic field direction of the stator. When the vector magnetic field of the stator rotates by an angle, the rotor also rotates by an angle with the magnetic field. Each time an electric pulse is input, the electric rotor will roll by an angle and go further. The output angular displacement is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Changing the winding energization sequence will cause the motor to rotate. Therefore, the number of pulses, frequency and the energization sequence of each phase winding of the motor can be controlled to control the rolling of the stepper motor.
