A reverse magnetic linear drive stepping motor

Abstract

The invention provides a reversed magnetic linear drive stepping motor, comprising a power unit and a transmission unit connected with the power unit, wherein the power unit comprises a reversed magnetic magnet and a coil group arranged at the periphery of the reversed magnetic magnet, and the transmission unit comprises a tooth row group and a ratchet group abutting on the tooth row group. The power unit is used for generating power, the transmission unit is used for transmitting the power of the power unit, during the power transmission of the transmission unit, after the reversed magnetic linear drive stepping motor receives a pulse signal, the coil set will generate a pulsed motion in the circumferential direction, the kinetic energy of the impulse motion is transmitted to the ratchetwheel group through the tooth row group, and the ratchet wheel of the ratchet wheel group can drive the tooth ring to rotate by a step angle, so that the structure of the diamagnetic linear driving stepping motor can be simplified, and the step control without out-of-step and with high precision can be achieved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an inverse magnetic linear drive stepping motor. Background technique [0002] Stepper motors mainly include three types: reactive type, permanent magnet type and hybrid type. The main structure is to improve the traditional rotor and stator design to comply with the digital control mode that converts electrical pulse signals into mechanical angular displacement. [0003] In the prior art, there are many problems in the stepper motor that will affect the output accuracy of its angular displacement. The main problem comes from the traditional rotor structure, including (1) when the pulse signal is input, the rotor will have a certain inertia residual effect after moving Its stop position; (2) no matter what kind of prior art, all there is distributing phenomenon, because the traditional rotor-stator structure is not suitable for receiving pulse signal. [0004] In addition, steppe...

Problems solved by technology

[0003] In the prior art, there are many problems in the stepper motor that will affect the output accuracy of its angular displacement. The main problem comes from the traditional rotor structure, including (1) when the pulse signal is input, the rotor will have a certain inertia residual effect after moving Its stop position; (2) No matter which kind of existing technology, there is a phenomenon of loss of distribution, because the traditional rotor stator structure is not suitable for receiving pulse signals

[0004] In addition, the stepper motors in the prior art need to rely on high-cost and complex motor structures to drive. First, the pulse signal needs to be distributed through a distributor, and then amplified by an amplifier to input the current into each phase separately, and then drive the motor to operate.

The components of the stepper motor require high precision and precise assembly, especially the key components that affect the torque, making the cost of the stepper motor high
