Stepper Motors and Brush Less DC Motors

auto4

Stepper motors are used for accurate, repeatable positioning such as machine tool applications or for moving the head in an ink-jet printer. By using an electronic controller that applies electrical pulses to the motor windings, the motor shaft can be rotated in either direction in multiples of the step angle, which can range from 0.720 (500 steps per revolution) to 150 (24 steps per revolution). Stepper motors are available with rotational accuracies on the order of 3 percent of a step, which is noncumulative as the motor is stepped back and forth. By controlling the rate at which pulses are applied to the windings of the stepper motor, speed can be varied continuously from a standing stop to a maximum that depends on the motor and load. The three main types of stepper motors are:

1.Variable-reluctance stepper motor 2.Permanent-magnet stepper motor 3.Hybrid stepper motors

The permanent-magnet stepper motor, which has a cylindrical rotor (called a tin-can rotor) that is permanently magnetized with north and south poles alternating around its circumference. The stator of the permanent magnet motor is similar to that of the reluctance motor. As in the reluctance type, the rotor position is stepped by applying a sequence of pulses to the stator windings. Hybrid stepper motors that combine variable reluctance with permanent magnets are also available.

Conventional dc motors are particularly useful in applications that require high speeds and in those for which dc power is available, such as those in aircraft and automobiles. However, because they contain commutators and brushes, conventional dc motors have several disadvantages. These include relatively short service lives due to brush and commutator wear, particularly at very high speeds. Also, arcing as the brushes move between commutator segments can pose a hazard in explosive environments and can create severe radio interference. A relatively new development, the brushless dc motor, provides an excellent alternative when the disadvantages of conventional dc motors are prohibitive. Brushless dc motors are essentially permanent-magnet stepping motors equipped with position sensors (either Hall Effect or optical) and enhanced control units.

As in the stepper motor, power is applied to one stator winding at a time. When the position sensor indicates that the rotor has approached alignment with the stator field, the controller electronically switches power to the next stator winding so that smooth motion continues. By varying the amplitude and duration of the pulses applied to the stator windings, speed can be readily controlled. The result is a motor that can operate from a dc source with characteristics similar to those of a conventional shunt dc motor. Brushless dc motors are used primarily in low-power applications. Their advantages include relatively high efficiency, long service life with little maintenance, freedom from radio interference, ability to operate in explosive chemical environments, and capability for very high speeds (50,000 rpm or more).

Ford Falcon-XR8 from Macarthur Automotive

auto7

Ford Australia just launched their all new Ford Falcon XR8 presenting new exterior and interior architectures and designs, all-new front suspension, advanced power trains, more torque, and most importantly, an improved fuel economy as well as a functional and efficient safety package.

The Ford Falcon XR8 has some similarities with the XR6 Turbo. The only difference is with the engine and with the signature power bulge. The modern Boss 290 5.4-liter four valve V8 engine boosts the XR8, not to mention its engine being complemented by a new exhaust systemthe Semi Active Muffler (SAM). The SAM gives out an unmatched, sporty V8 exhaust note, while it delivers a better kind of interior environment.

Strictly speaking in pure visual terms, the interiors of Ford Falcon XR8 have a classic look that is highlighted by soft blue night-time dashboard lighting and splashes of chrome. The stereo also is now better compared to previous makes. A six-disc MP3-compatible CD changer is matched to an eight-speaker 150W amplifier and subwoofer package, giving out a great solid sound all through out the vehicle.

When it comes to riding or driving the Ford Falcon XR8, despite its bulk at the front end, the XR8 seems to be more balanced than Ford GTs speed. You can pretty much accelerate pleasantly with XR8 since its only highlighted by smooth changes in the ZF 6-speed automatic gearbox. In addition, XR8s sequential sports shift is also handy since it anticipates and monitor whatever driving style you have which can sometimes let you stay in a low gear for a longer time.

The Ford Falcon XR8 is the very first Australian built car to garner a five star safety rating from the Australasian New Car Assessment Program, also known as ANCAP. It scored 34.6 out of 37 points and received five stars for passengers safety which prove that Ford Falcon XR8 can be one of the safest cars ever made.

There is no ignoring that Auto SMS Systems are now assuming their due place on the internet marketing arena. While global corporations have been making use of continuous and mass communication strategies for years, including 24/7 customer outreach via off-shoring and follow-the-sun approaches, Auto SMS marketing has put this tactic well into the reaches of small and medium organizations. Auto SMS systems are an effective way to quickly and cheaply distribute your marketing message to a sea of potential consumers.

SMS marketing is taking on an ever greater role in influencing consumer behaviour as more and more consumers use their mobile and smart devices to make purchasing decisions. SMS marketing has come a long way since the old internet marketing or email-based marketing approaches. While they have no-doubt been born out of internet marketing and web-based advertising, the popularity of SMS marketing and Auto SMS Systems has increased of late, thanks mainly to the demand for mobile smart devices. While many internet marketing strategies are ‘pull’ based, depending on consumers to initiate contact with a website, SMS marketing offers organizations a more proactive ‘push’ based approach to connect with its customers. Using quick response technologies, such as smart mobile devices, consumers are more prone to respond positively to a well designed SMS message and in the process commit to an ‘impulse buy’.

Using test message marketing could be one method to measure the effectiveness of an Auto SMS System before you subscribe to a service or buy a tool. Through use of a test message marketing strategy, one can measure the effect of the marketing campaign on a pilot group before mass broadcasting the SMS message. Many Auto SMS System providers and carriers permit either a handful or an unlimited number of test messages. Sending test messages to yourself through your Auto SMS System, and then verifying key aspects of the message is a good way to validate your SMS message marketing strategy.

Even “minor” issues with things like font sizes and colour can be highlighted with a well planned test message marketing strategy. Sometimes, Auto SMS System providers impose restrictions on the size of an SMS message. Such limitations may seem restrictive, but when used in conjunction with other complimentary SMS messages, can result in greatly determine consumer choices.

Similar to conventional phone, mail and even email marketing, Auto SMS Systems may also be subject to legislation. Industry overseers and mobile phone carriers have guidelines to determine fair use of SMS messages, including consumer choice to opt-in/out of an SMS marketing campaign. Failure to abide by these rules can lead to severe penalties or being barred from carrying out business over a carriers network.

If you already own a vessel and are unhappy with it’s performance, there are a couple of alternatives available to you. Whilst your vessel might still be in a high quality condition, your dissatisfaction might exist with the power coming out of your outboard motors. Instead of purchasing a new vessel you may be able to simply eliminate your dissatisfaction by investing in Yamaha outboards or Mercury outboards to suit your need for extra power or performance. This choice would be able to save a boat enthusiast a considerable amount of cash since the exchanging of an old outboard motors to Yamaha outboards or Mercury outboards is quite a simple task.
