Microcontroller Based Dc Motor Conditioning and Monitoring System

In this paper a project is proposed to separate the objects from a set according to their colors. This can be useful for categorization of the objects which move on a conveyer belt. The proposed method of categorization is based on color of the object. In this project the system categorization of different colors. The detection of the particular color is done by a light intensity to frequency converter method. The robotic arm is controlled by a microcontroller based system which controls DC motor for picking up the specified color from a moving objects conveyer belt.

Cogging torque of electrical motors is the torque due to the interaction between the permanent magnets of the rotor and the statorslots of a Permanent Magnet (PM) machine. It is also known as detent or 'no-current ' torque. This torque is position dependent and its periodicity per revolution depends on the number of magnetic poles and the number of teeth on the stator. Cogging torque is an undesirable component for

In this manner the timing can be improved to suit all motor speeds and conditions

The electricity from the positive and negative end of the battery and flows through the wire and makes the wire spin but you need to have the magnet for the wire to spin. You can change the way the wire spins but flipping the magnet over. The motor uses the attracting and repelling forces to make the wire spin. If you use stronger magnets the force will be greater. If you coil the wire more the magnetic field will get larger. But you cannot put to many coils in it or it will become too heavy. If you have wire with a coating you will have to scrap it off for it to work. If you put the support braces to far apart that can also become a problem. You can predict what way the wire or motor is going to spin.

High Speed Operation – A BLDC motor can operate at speeds approximately ten thousand revolutions per minute under loaded and unloaded conditions.

Manual modes also avoid the power requirement of the hydraulic control system, by relying on the human muscle power of the vehicle operator to disengage the clutch and actuate the gear levers. Thus the manual transmission requires very little engine power to function, with the main power consumption due to drag from the gear train being in the lubricating oil of the gearbox.

After the decisions regarding the body structure, it’s the time for designing the heart of the robot. Similar to many RC cars and other mini robot vehicles, using DC motors with a great package of speed reducer gearbox would be the best method to run the vehicle. In this section, I express a brief description of the DC motors and the chosen speed reducer gears, then next chapter would include more details regarding the relation between the motors and the power moves the vehicle with all the accessories. Also, it should be strong enough to supply the enough digging force when supporting the arm.

Motors are widely used to actuate various devices in the field of engineering. The motor’s ability to induce motion at a wide range of scales from small toy car motors to large industrial fans allow engineers to apply them to a wide variety of situations. Reverse-engineering or testing Or Testing Of Motors (MOTOЯ), Inc is concerned with the potential applications of three different types of motors; stepper motors, servo motors and DC and assigned a team to test these three motors and report the best use for each one. The purpose of this experiment was to test the different types of motors, report the best case application for each one and recommend a motor for the company’s new robotic surgery system.

Wheref_BRG is the characteristic fault frequency for bearing failure, f_s is the supply frequency for motor, m is any integer, f_ir and f_or are characteristic frequencies for inner and outer ring respectively. Extensive knowledge of bearing design is required for an exact calculation. However, in practice, these frequencies are commonly

Given the information provided, a decision was made to use 1 hp motors. Because these motors will be working for extended periods of time under varying load conditions, it seemed unwise to choose motors which would be operating at peak performance consistently. Also, the difference between a ¾ hp motor and a 1 hp motor was found to be only $23. REFERENCE

Motion sensing is the technique in which a system detects a change in position of an object with respect to its surroundings. This paper gives an overview of motion sensors and its applications, and also points out the problems associated with them.

BRIEF DESCRIPTION OF MOTORS AND DRIVES: In this segment, I will briefly review the diverse types of variable-speed drives used in the industry. For the most part, electronic AC and DC drives find their domination in manufacturing and commercial HVAC uses of today. This brief look at drive machineries will assist you, should you encounter any of these types in the future. In addition, I will also review the benefits and limits of each type.

The electrical power is alternating current but DC motors needs a rectifier to convert that into direct current.

Generator, batteries and an electronic control unit (ECU). The motor or generator is coupled to the live axle using an electric clutch mechanism which is actuated by the ECU. While braking the kinetic energy is absorbed by the generator which converts it into electric impulse, in this part of the cycle, the motor/generator acts like a generator. This energy is stored in the batteries. Most preferred batteries are of Li-ion type. On the command of the driver, the ECU directs the power to be given back to the differential, this is when the motor uses the stored electric energy from the battery pack to give an

The project is for limiting the speed of the vehicles running on the road. In day to day life people ride their vehicles at very high speed without caring for the speed limit fixed by the government for the particular road on which they are travelling. This gives rise to huge number of accidents. The whole control system consists of frequency receiver, speed sensing element, microcontroller and some modification in wiring with relay which is described above. On every road, some speed limit is already decided by the government which should be strictly followed by the vehicle’s driver. The limited speeds may be 20 kilometer per hour, 40 kilometer per hour, 60 kilometer per hour, 80 kilometer per hour or any other speed limit. The number of speeds to be limited may be any as per government decision. For every speed limit an unique frequency will be allotted. The frequency transmitters will be placed at certain interval of distance so that the whole road is covered with the frequency being transmitted and the circuit can receive the frequency.
