quality Micro Stepper Motor & Permanent Magnet Stepper Motor manufacturer

The application of stepper motors will encounter nine major problems   1, how to control the direction of rotation of the stepper motor?   You can change the direction level signal of the control system. You can adjust the wiring of the motor to change the direction, as follows: For two-phase motors, just one of the phases of the motor line exchange access stepper motor driver can be, such as A + and A- exchange. For three-phase motors, not one of the phases of the motor line exchange, but should be sequential exchange of the two phases, such as the A + and B + exchange, A- and B- exchange.   2, the stepper motor noise is particularly large, no force, and the motor vibration, how to do?   This situation is encountered because the stepper motor work in the oscillation zone, the solution. A, change the input signal frequency CP to avoid the oscillation zone. B, the use of subdivision drive, so that the step angle is reduced, running smoothly.   3, when the stepper motor is powered on, the motor shaft does not turn how to do? There are several reasons why the motor does not rotate. A, overload blocking rotation B, whether the motor has been damaged C, whether the motor is in the offline state D, whether the pulse signal CP to zero   4, stepper motor driver power on, the motor is shaking, can not run, how to do?   Encounter this situation, first check the motor winding and the driver connection and no wrong connection, such as no wrong connection, and then check the input pulse signal frequency is too high, whether the lift frequency design is not reasonable.   5, how to do a good job of stepper motor lift curve?   The speed of the stepper motor is changing with the input pulse signal. Theoretically, just give the driver pulse signal. Each give the driver a pulse (CP), the stepper motor rotates a step angle (subdivision for a subdivision step angle). However, due to the stepper motor performance, CP signal changes too quickly, the stepper motor will not be able to keep up with the changes in electrical signals, which will produce blocking and lost steps. So the stepper motor to be at high speed, there must be a speed-up process, in stopping there must be a speed-down process. General speed up and down the same law, the following speed up as an example: speed up process consists of jump frequency plus speed curve (and vice versa). The start frequency should not be too large, otherwise it will also produce blocking and lost step. The speed up and down curves are generally exponential curves or adjusted exponential curves, of course, can also use straight lines or sine curves, etc.. Users need to choose the appropriate response frequency and speed curve according to their own load, and it is not easy to find an ideal curve, and it usually requires several trials. Exponential curve in the actual software programming process is more troublesome, generally calculated in advance time constants stored in the computer memory it, the work process directly selected.   6, stepper motor hot, what is the normal temperature range?   Stepping motor temperature is too high will demagnetize the magnetic material of the motor, resulting in a drop in torque and even loss of step. Therefore, the maximum allowable temperature of the motor exterior should depend on the demagnetization point of different magnetic materials. Generally speaking, the demagnetization point of magnetic materials are above 130 degrees Celsius, and some are even higher. So stepper motor appearance in 80-90 degrees Celsius is completely normal.     7, two-phase stepper motor and four-phase stepper motor what is the difference?   Two-phase stepper motors have only two windings on the stator with four outgoing wires, 1.8° for the whole step and 0.9° for the half step. In the drive, it is enough to control the current flow and current direction of the two-phase winding. While four-phase stepper motor in the stator has four windings, there are eight wires, the whole step is 0.9 °, half-step for 0.45 °, but the driver needs to control the four windings, the circuit is relatively complex. So two-phase motor with two-phase drive, four-phase eight-wire motor has parallel, series, single-pole type three connection methods. Parallel connection: four-phase winding two by two, the winding resistance and inductance decreases exponentially, the motor runs with good acceleration performance, high speed with a large torque, but the motor needs to input twice the rated current, heat, the drive output capacity requirements correspondingly increased. When used in series, the winding resistance and inductance increases exponentially, the motor is stable at low speed, noise and heat generation is small, the requirements for the drive is not high, but the high-speed torque loss is large. So users can choose the four-phase eight-wire stepper motor wiring method according to the requirements.   8, the motor is four-phase six lines, and stepper motor driver as long as the solution to four lines, how to use?   For four-phase six-wire motor, the middle tap of the two wires hanging not connected, the other four wires and the driver is connected.   9, the difference between reactive stepper motors and hybrid stepper motors?   Different in structure and material, hybrid motors have permanent magnet type material inside, so hybrid stepper motors run relatively smoothly, with high output floating force and low noise.  

Small body, big energy, take you into the world of micro motor Do not look at the miniature motor so small, its small body but contains a lot of energy Oh! Micro motor manufacturing processes, involving precision machinery, fine chemicals, microfabrication, magnetic material processing, winding manufacturing, insulation processing and other process technologies, the number of process equipment required is large, high precision, some micro motors may have a higher technical content than ordinary motors. According to the height of the base foot plane to the center of the shaft, motors are mainly divided into large motors, small and medium-sized motors and micro motors, of which, motors with a center height of 15mm-71mm are micro motors. This is the most basic feature to identify the micro motor, next, let's look at the definition of micro motor in the encyclopedia. "Micro motor (full name miniature special motor, referred to as micro motor) is a kind of volume, capacity is small, the output power is generally below a few hundred watts, the use, performance and environmental conditions require a special class of motor. It refers to the motor with diameter less than 160mm or rated power less than 750W. Micro motors are often used in control systems or transmission mechanical loads for the detection, analysis operation, amplification, execution or conversion of electromechanical signals or energy, or for transmission mechanical loads, and can also be used as AC and DC power supplies for equipment. Such as disk drives, copiers, CNC machine tools, robots, etc. have applied micro motors."     From the working principle, the micro motor is converted into mechanical energy through electrical energy. The rotor of the micro motor is driven by the current, the different rotor current direction produces different magnetic poles, resulting in interaction and rotation, the rotor rotates to a certain angle, through the commutator's commutation function can take the current direction to change the rotor magnetic polarity change, keep the rotor and stator interaction direction unchanged, so that the micro motor began to rotate non-stop. In terms of the types of micro motors, micro motors are divided into three main categories: drive micro motors, control micro motors and power micro motors. Among them, the driving micro motors include micro asynchronous motors, micro synchronous motors, micro AC commutator motors, micro DC motors, etc.; the control micro motors include self-tuning angle machines, rotary transformers, AC and DC speed generators, AC and DC servo motors, stepper motors, torque motors, etc.; the power micro motors include micro electric generator sets and single armature AC machines, etc. From the characteristics of micro motors, micro motors have the advantages of high torque, low noise, small size, light weight, easy to use, constant speed operation, etc. They can also be matched with a variety of gearboxes to achieve the purpose of changing the output speed and torque.
