Choosing a stepper motor, first of all to ensure that the stepper motor output power is greater than the power required to load. And when choosing power stepping motor, first to compute the mechanical system of load torque, the torque of the motor frequency characteristics can satisfy the mechanical load and has a certain margin to ensure its reliable operation. In the process of practical work, various frequency under the load torque must be within the scope of the torque-speed characteristic curve. Generally the maximum static torque Mjmax big motor, load torque. Should make when choosing a stepper motor step Angle and mechanical system matching, so that we can get the pulse equivalent machine tools required. In the process of mechanical transmission in order to have a smaller pulse equivalent, it is can change the lead screw, 2 it is can be done through stepping motor subdivision driver. But can only change the resolution, segment does not change its precision. Accuracy is determined by the inherent characteristic of the motor. Select power stepping motor, it shall estimate the load moment of inertia of the mechanical load and machine tools required start frequency, make it match the inertia frequency characteristics of stepping motor and certain allowance, work of the high speed continuous frequency can meet the needs of the fast moving machine tool. We often see all kinds of motor, internal are core and the windings. Winding resistance, electricity will produce loss, the loss is proportional to the square of the size and the resistance and current, this is the copper loss, we often say that if the current is not a standard dc or sine wave, will also produce harmonic loss; Core has hysteresis eddy current effect, also can produce loss in the alternating magnetic field, its size and material, current, frequency, voltage, this is called iron losses. Copper loss and iron loss will be displayed in the form of heat, which affects the efficiency of the machine. Stepper motor general pursuit of position precision and torque output, the efficiency is low, the current is compared commonly big, high harmonic components, the frequency of the alternating current is also change with speed, thus stepping motor are widespread fever, than the general ac motor serious condition. 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.
