This paper highlights the system requirements and operating conditions of automatic air recirculation valves and reviews compatibility of existing actuator types with these requirements. When comparing the available technologies, it becomes clear that air recirculation flap actuators containing a bipolar stepper motor offer key advantages over actuators with other motor types. It is shown how s...

An Arduino-based stepper motor was used to create a nanofiber spinning machine. The hardware for this tool includes an Arduino Mega module, 4x4 keypad, TM1637 type seven-segment display, and L298N driver, 17Hs4401 motor, Pushbutton, ultrasonic sensor. software utilized is the IDE, which written in C. This tool's operating premise that processes input from Keypad, then Stepper Motor Driver drive...

Stepper motor is found in a lot of applications such as computer peripherals, business machines, process control, machine tools and robotics. Especially in different areas of robotics, process control like silicon processing, I.C. Bonding and Laser trimming applications, it is necessary to control the stepper motor from remote places. The present paper describes a remote angular position contro...

the depth control systems used in iranian tractors are mechanical and they produce variable tillage depth in uneven field surface. in this research a rotary type electronic control valve was designed and constructed. by using this valve, electro-hydraulic tillage depth control system was developed and installed on the tractor. the control system was composed of: a depth sensor, a programmable l...

On the basis of predecessors' research and the existing theory, for convenient and reliable to study the biological effect of low frequency rotating magnetic field, design a high precision and low frequency rotating magnetic field generator, which could be used to stimulate the small area. Choose stepper motor to drive permanent magnet for produce a rotating magnetic field, which can reduce the...

This paper addresses the design and commutation of a novel kind of spherical stepper motor in which the poles of the stator are electromagnets and the poles of the rotor (rotating ball) are permanent magnets. Due to the fact that points on a sphere can only be arranged with equal spacing in a limited number of cases (corresponding to the Platonic solids), design of spherical stepper motors with...

36 Elektor Electronics 11/2003 Often a mechanical operation is required in an application to accurately position a load or device. While a conventional DC or AC motor can be used, it is difficult to determine the exact position of the load, motor speed, or how much total motion has been produced, unless external positioning sensors, encoders, servo loops, and controlling devices (brakes or clut...

This paper describes the stepper motor position control implemented using a novel nonsingleton type-1 fuzzy logic system to update the gains of the professional proportional-integral-derivative controller running on ATMEGA 2560 microcontroller. In this work, three controllers are compared: a) the professional proportional-integral-derivative controller, b) the type-1 singleton fuzzy logic syste...

Motor stepper tidak sama dengan motor AC maupun DC konvensional yang berputar secara kontiniu,tetapi perputaran pada yaitu incremental atau langkah per ( step by ), sehingga dapat memberikan putaran lebih presisi dan akurat.Perancangan pembuatan system pengendali arah berbasis ICL293D sangat menarik untuk dipelajari.Dalam perancangan ini menggunakan metode eksperimen,sehingga dalam simulator di...

To successfully follow a velocity profile, a motor and drive combination must generate enough torque to: accelerate the load inertia at the desired rates, and drive the load torque at the desired speeds. While the size of a bipolar stepper motor generally dictates the low speed torque, the ability of the drive electronics to force current through the windings of the motor dictates the high spee...
