The four lower transistors are usually directly driven by the microcontroller, while the upper transistors need the upper drive circuit with higher cost. The Stratotimer 3ATI Advanced Multifunction Aircraft Chronograph can easily replace old devices such as the ADS Transicoil/Astrotech LC-90/LC-90SR clocks etc. The number of transistors in the drive circuit of bipolar stepper motor is twice that of unipolar drive circuit. 4 - wire stepper motor can only use bipolar drive circuit, which greatly reduces the cost of mass production application. Bipolar drive circuit can drive 4 - wire or 6 - wire stepper motor at the same time. The two groups of phases are driven by eight transistors. The driving circuit of bipolar stepper motor is shown in the figure 2. Besides, the resistor improves the performance of high frequency. It makes the back edge of the current pulse in the winding steeper, and reduces the current drop time.

200 Ω resistor in series with freewheeling diode can reduce the discharge time constant of the circuit. D1 ~ D4 are freewheeling diode, through which the back EMF generated by the motor winding fades, thus protecting the power transistor TIP122 from damage.ĥ0 Ω external resistor is connected in parallel with a 200 μ F capacitor, which can improve the current pulse front of the stepper motor winding and improve the high frequency performance of the stepper motor. Untuk informasi datasheet dan data pin transistor pengganti, silahkan buka link pada tipe transistor dengan mengklik-nya. RL1 ~ RL4 shown in Figure 1 are winding internal resistor, while 50 Ω Resistor is an external resistor, which can limit the current and improve the time constant of the circuit. Berikut ini adalah daftar tabel persamaan transistor lengkap yang biasa digunakan pada berbagai rangkaian elektronika. Therefore, the heating condition is common in stepper motor, especially compared with AC motor. And the frequency of alternating current changes with the speed. The stepper motor generally pursues positioning accuracy and torque output with low efficiency, large current, and high harmonic composition. The size of the iron core is related to material, current, frequency and voltage, which is called iron loss.Ĭopper loss and iron loss are reflected in the form of heat, affecting the efficiency of the motor. There is hysteresis eddy current effect in the iron core, producing loss in alternating magnetic field. If the current is not a standard DC or sine wave, it will also produce harmonic loss. If the winding is with a resistance, there will be electric loss which is proportional to the square of resistance and current. The internal of common types of motors are iron core and winding coil. Kelebihan 2SC5200 yaitu gain arus dan arus kolektor-nya yang tinggi, transistor ini sangat umum digunakan dalam sirkuit audio berdaya tinggi atau amplifier. Transistor 2SC5200 adalah transistor jenis NPN pabrikan dari Toshiba. So the control of pulses’ number, frequency and the power on sequence of each phase winding of the motor affect the rotation of the stepper motor. Tidak hanya itu Kami juga memberikan datasheet transistor 2SC5200 yang bisa Kamu download secara gratis. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency.Ĭhanging the order in which the winding is energized will reverse the motor. Every input of an electric pulse leads the motor to rotate at an angle to advance one step. When the vector magnetic field of the stator rotates an angle, the rotor also rotates at an angle with this magnetic field. The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator.
When the current flows through the stator winding, the stator winding produces a vector magnetic field.
