Stepper motor in three kinds: permanent magnet (PM), equation (VR）And hybrid (HB）。 Permanent magnet stepping, generally for two phase, torque and volume is small, step Angle is commonly 7. 5 or 15 degrees; Reactive step for three-phase commonly, can achieve high torque output, stepper Angle generally to 1. 5 degrees, but the noise and vibration are very big. In Europe and the United States and other developed countries have been eliminated in the 80 s; Hybrid stepping refers to a mixture of permanent magnet and the advantages of reactive. It is divided into two and five phase: two phase stepper Angle generally to 1. 8 degrees and five phase stepping Angle generally is 0. 72 degrees. The application of the stepper motor is more widely. Stepper motor temperature will make the first motor demagnetization of magnetic materials, which can lead to torque decline and even out of step, so the motor appearance allows the highest temperature should depend on different points of demagnetization motor magnetic material; Demagnetization of magnetic materials, in general, some are above 130 degrees Celsius, some even as high as 200 degrees Celsius above, so the temperature in Celsius 80 - stepper motor appearance90 degree completely normal. To sum up four sentences 1. Advantages: easy control, low cost. 2. Disadvantages: step will cause error control, speed limited. 3. Application: CNC machine tools, quantitative feeding, etc. 4. Outlook: will gradually be replaced by stepper motor stepper motor as the executive element, is one of the key products of electromechanical integration, widely used in all kinds of automation control system. With the development of microelectronics and computer technology, increasing demand for stepper motor, are used in the field of the national economy. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
