stepper motor
There was an article published recently about a piezo electric motor that was infrared driven. The heat bent the element and it moved the motor.
DC motors use PWM (pulse width modulation), which can easily increase or decrease the power to the motor, thereby increasing or decreasing the motor speed by modulating the width of the pulse. Stepper motors have fixed frequencies, thereby having fixed motor speeds. As a result, the speed of the stepper motor cannot be controlled when the load is increased.
A: A stepper motor move a step at the time. If you know the steps then you will know the speed per tum. The motor need current pulses with a fast rise time the width is immaterial once moved
idle is controlled through the engine control module. the input is the throttle sensor the output is the idle speed stepper motor. The motor should be removed and the motor and throttle body should be cleaned.
A normal motor run at a fixed speed depending on: AC motors: Voltage and frequency (Hetz) and number of poles DC Motors: Armature voltage Stepper motors speed depend on the drive pulse frequency.
Stepper idle speed actuator in carbureted vehicles it is used to control the engine's idling RPM. It also regulates the position of the throttle valve plate.
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.
A stepper motor is a type of electric motor that divides a full rotation into a series of discrete steps, allowing for precise control of angular position and speed. Each step corresponds to a specific degree of rotation, enabling accurate positioning without the need for feedback systems. Stepper motors are commonly used in applications such as 3D printers, CNC machines, and robotics, where precision and repeatability are essential. Their ability to maintain position when powered makes them ideal for open-loop control systems.
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.
The efficiency of a bipolar stepper motor compared to a unipolar motor has to be determined by the individual. If you are using the motor in a high speed situation, the unipolar motor is more efficient in those situations. For lower speed situations, the bipolar stepper motor is more efficient. Unipolar motors will have less torque at lower speeds, while bipolar motors will have less torque at higher speeds.

1. Once motor is not controled well, it can easily cause resonance vibration.2. Hardly to run to the higher speed.
