Stepper motor performance can be compromised by noise and vibration, but an advanced high-torque micro-stepping algorithm can minimise the impact of both noise and vibration as well as increasing the resolution of the rotations. The embedded microcontroller which hosts the micro-stepper algorithm also provides additional flexibility to integrate current-limiting as well as adjusting the drive c...
Abstract In the field of industrial control, stepping has been widely used as an actuator. For this article, based on STM32F103 control core, functions start and stop, forward rotation, reverse rotation speed regulation motor are realized through four buttons. The system uses L293D to drive a stepper motor, LED0 LED1 two status lights display motor’s status, digital tube displays current speed....
Today, modern technologies tend to develop rapidly. The application of advanced inventions, principles, systems and approaches allows simplify the production process, reduce cost manufacturing finished products, replace monotonous manual work with automated devices. basis power drive such are electric motors: permanent magnets, direct current, stepper, etc. When developing any electromechanical...
PURPOSE To demonstrate that high-resolution biometry is possible in mouse eyes in vivo, using real-time OCT with focal plane advancement by a stepper motor. METHODS OCT images of eyes were taken from nine 29-day-old C57BL/6 mice(18 eyes) on two consecutive days. A custom-built real-time OCT instrument with a stepper motor was used to advance the focal plane from the corneal apex to the retina...
The shuffle motor is a linear electrostatic stepper motor employing a mechanical transformation to obtain large forces and small steps. A model has been made to calculate the step size and the driving voltage as a function of the load force and the motor geometry. The motor consists of three polysilicon layers and has been fabricated using surface micromachining. Tests show an effective step si...
In the mobile robot navigation, the ultrasonic sensors have been widely used for the obstacles detection and map building because of its cost and efficiency. Generally sensors are used to increase the accuracy of the obstacles position and decrease the time. In this paper an ultrasonic sensor is interfaced on to a stepper motor which will be constantly revolving and detecting the values of any ...
