What is a hybrid step motor?
Step Angle: the angular displacement of the rotor of an electric motor corresponds to a pulse signal. In general, the step distance of the second phase motor is 1.8 degrees. Static TORQUE (HOLDING TORQUE) : the TORQUE of the stator lock on the rotor when the stepper motor is running at the rated current but does not rotate. It is one of the most important parameters of the stepping motor, which is usually the torque at low speed. DETENT TORQUE: it is the moment when the motor is not connected to the motor. Step Angle accuracy: the actual value and theoretical error of each step Angle of the step motor. Percentage: (error/step Angle)? 0? 7 100%. The error of step Angle does not accumulate. Maximum no-load start frequency: motor in some form of driver, rated voltage and power flow, in the case of without load, can directly start the biggest frequency. Maximum running frequency: the maximum operating frequency of the motor without load, in some type of drive, voltage, and rated power.
Stepping motor is one of the key products of electromechanical integration and is widely used in all kinds of automatic equipments. Stepper motor and the difference is that it is a kind of ordinary motor electrical pulse signal into angular displacement of the actuator, it completed two jobs at the same time: one is transmission torque, 2 it is to control the Angle position or velocity. Principle of electric motor: the schematic of working principle of two-phase step motor, it has two winding. When a winding is energized, its stator magnetic pole generates a magnetic field, which absorbs the rotor to the pole. If the winding is in the control pulse, the general electric direction sequence is changed in four states, and the motor can rotate clockwise. When the electricity is in sequence, the motor turns counterclockwise. Once every action of the control pulse, the general electric direction changes once, making the motor move one step, namely 90 degrees. Four pulses, and the motor turns around. The higher pulse frequency, the faster the motor rotation, section structure than actual motor model is complex, and every step, is usually 1-8 °. Stepper motor output torque and effective volume of the motor, coil is directly proportional to the number of turns, the magnetic flux and current, therefore, effective volume, the greater the motor excitation, the greater the number of ampere turns on the air gap between rotor is smaller, the motor torque is larger, the smaller and vice. Step forward motor term: phase number: refers to the number of coils within the machine. Currently, two phases, three phases, four phases and five phase stepping motors are commonly used.
Hybrid stepper motor: the step motor is divided into three types: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 1.5 degrees. The reaction type step is generally three-phase, can realize the big torque output, the step Angle usually is 1.5 degrees, but the noise and vibration are very large. Developed countries such as the United States and Europe were eliminated in the 1980s. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phase, three-phase and five phase: two phase stepper Angle of 1.8 degrees commonly and five phase stepping Angle of 0.72 degrees commonly, hybrid stepping motor as the increase of the number of phase (several) winding the power supply, the stepping Angle decreases, and improve the precision and the application of the stepper motor is more extensive
