Can we interfacing stepper motor using 8086?
Yes, you can interface a stepper motor using the 8086 microprocessor. This typically involves using output ports to send control signals to a motor driver circuit, which then drives the stepper motor. You would need to write a program to generate the appropriate sequences of pulses to control the motor's direction and speed. Additionally, external components like transistors or H-bridges may be required to handle the motor's current.
Is it possible to synchronize stepper motor with joystick using relays and how?
dont know !!HAHA
How do you change a degree of rotation in stepper motor using 8085 microprocessor?
To change the degree of rotation in a stepper motor using an 8085 microprocessor, you first need to determine the number of steps required for the desired rotation. This is done by calculating the steps per degree based on the stepper motor's specifications. Then, you can write a program in assembly language to control the motor's step sequence using output ports connected to the motor driver. By sending the appropriate sequence of signals for the calculated number of steps, you can achieve the desired rotation.
How do you use flip flops and logic gates to provide the proper sequence logic to sequentially energize the phase windings of a four phase stepper motor?
Unfortunately there isn't enough information to give you a complete answer. Which stepper motor are you using?
Descibe 8086 interfacing of stepper motor to rotate it through 90 degree using 8255?
To interface a stepper motor with the 8086 microprocessor using the 8255 Programmable Peripheral Interface (PPI), you first configure the 8255 in mode 0 for simple I/O operations. The control lines of the stepper motor are connected to the output ports of the 8255. The microprocessor sends a sequence of pulses to these ports to energize the motor coils in the correct order, effectively rotating the motor in steps. To achieve a 90-degree rotation, the number of pulses sent corresponds to the required steps based on the step angle of the motor (e.g., for a 1.8-degree stepper, you would send 50 pulses).
How to Reverse the direction of a stepper motor?
Suppose if u r using four pole stepper motor. keep the first coil on then energize second coil. and then again energise the first coil instead third coil. you will get reversed now.. all the best
Is a bipolar stepper motor more efficient than a unipolar 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. A full explanation with diagrams is available on the website: http://www.nmbtc.com/step-motors/engineering/drivers-and-winding-configuration.html
Where can I find a cheap bipolar stepper motor?
By using your web browser, you can find what you need fairly easily. www.anaheimautomation.com has these motors for under $12. Shipping will cost somewhere around $8 for your motor.
What is a common use for a stepper motor?
Applications of Stepper Motor: Computer-controlled stepper motors are one of the most versatile forms of positioning systems. They are typically digitally controlled as part of an open loop system, and are simpler and more rugged than closed loop servo systems. Industrial applications are in high speed pick and place equipment and multi-axis machine CNC machines often directly driving lead screws or ballscrews. In the field of lasers and optics they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery, and positioning of valve pilot stages for fluid control systems. Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, and many more devices. Some people looking for generators for homemade Wind Turbines found success in using stepper motors for generating power.
Is it advisable to use a separate micro-controller for servo motor controller of a robot rather than using only one micro-controller for the whole system and why?
Yes, most MCU's can not multi task it can run only one program at a time, so if you run a stepperor servo motor from one MCU it will slow down the whole program so, if you have send the command from the main MCU to the other one that is controlling the stepper or servo the main MCU can go on doing other things while the stepper MCU can take its time taking the stepper motor thru its paces If you have to run more than one stepper and using only one MCU, the MCU will have to drive the one stepper with one pulse and then the next stepper, you don't need a large MCU to drive a stepper only 4 bits is needed a 8 pin PIC like the PIC12F675 is all you need, GP0 to GP3 can drive the stepper while the chip can receive commands on GP5 that is a input pin only ,then you still have GP4 spare to drive a LED or a relay or you can use it as a DTR to send an interrupt to the main MCU and tell it that its done with the last command and ready for the next. A string of commands can be received by the 12F675 in serie on one pin and be stored in onboard EEPROM for use as needed
Braking characteristics for ac and dc drives?
There are many electronic ways to brake AC and DC motors the construction of the motors also influence the braking alternatives that can be chosen.most AC motors can by braked very effectively with a short burst of DC, this locks up the motor very rapidly but may take its toll on the DC supply components , rectifiers contractor's etc. Obviously as its stalling the motor it may also have physical consequences on the mechanical parts involved as well.An AC car wheel balancer as seen in tyre fitting shops often use DC to slow the motor then also use DC to hold the motor while the operator adds weights.DC motors can generally be braked by using them as generators, a good example is the regenerative braking systems being designed into modern hybrid vehicles, In a sense they are being used as generators to recharge the battery system.Until the batteries are fully charged this can be arranged so it is almost as effective as shorting out the motor to magnetically lock it up, there has to be a bit of dynamic impedance matching so that the motor sees a very low impedance,Some motors such as stepper motors have some inherent braking, if you take a small stepper motor from an old printer you will feel as it rotates it steps to the next position, this can be easily exaggerated by twisting the drive wires together to short out the stepper,The permanent magnet within the stepper tries to become a generator into the shorted coils and will often lock the motor solid.
What are the benefits to using a brushless dc motor drive?
There are many benefits to using a brushless dc motor drive. For instance, they utilize electronic systems rather than manual ones, and their torque current and frequency of speed relationships are linear.
