a stepper motor, also known as step motor or stepping motor, is a brushless dc electric motor that divides a full rotation into a number of equal steps. the motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback an open-loop controller , as long as the motor is carefully sized to the application in respect to torque and speed.
torque converter elements. a fluid coupling is a two element drive that is incapable of multiplying torque, while a torque converter has at least one extra element—the stator—which alters the drive's characteristics during periods of high slippage, producing an increase in output torque.
the product of μ and m is the factor of adhesion, which determines the maximum torque that can be applied before the onset of wheelspin or wheelslip. starting tractive effort: starting tractive effort is the tractive force that can be generated at a standstill. this figure is important on railways because it determines the maximum train weight .
a brushless dc electric motor bldc motor or bl motor , also known as electronically commutated motor ecm or ec motor and synchronous dc motors, are synchronous motors powered by direct current dc electricity via an inverter or switching power supply which produces electricity in the form of alternating current ac to drive each phase of the motor via a closed loop controller.
the chevrolet 'big block' is a term for a series of large displacement v8 engines that have been developed and produced in the united states from the 1950s until 2009. as american automobiles grew in size and weight following the second world war, the engines powering them had to keep pace.chevrolet had introduced its popular small block v8 in 1955, but needed something larger to power its .
a modern watch mainspring is a long strip of hardened and blued steel, or specialised steel alloy, 20–30 cm long and 0.05-0.2 mm thick. the mainspring in the common 1-day movement is calculated to enable the watch to run for 36 to 40 hours, i.e. 24 hours between daily windings with a power-reserve of 12 to 16 hours, in case the owner is late winding the watch.
the power band of an internal combustion engine or electric motor is the range of operating speeds under which the engine or motor is able to operate most efficiently. while engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range. specifically, power band is the range of rpm around peak power output. the power band of an internal combustion gasoline automobile engine typically sta

the moto guzzi stelvio 1200 is a dual-sport . engine comes from the griso/breva series and has been optimized with modified camshafts for an improved torque curve. engine. the motor is an .
an induction motor or asynchronous motor is an ac electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. an induction motor can therefore be made without electrical connections to the rotor. an induction motor's rotor can be either wound type or squirrel-cage type. three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliab
a brushed dc electric motor is an internally commutated electric motor designed to be run from a direct current power source. brushed motors were the first commercially important application of electric power to driving mechanical energy, and dc distribution systems were used for more than 100 years to operate motors in commercial and industrial buildings.
an electric motor e-motor test stand also referred to as bench is a test stand for reproducible testing of electric motors.in addition to the mechanical design, an electric motor test stand consists of accompanying measurement devices, sensors and application software.the bus systems used to control and monitor the test objects are also included in the test stand.
a torque motor is a specialized form of dc electric motor which can operate indefinitely while stalled, without incurring damage. in this mode of operation, the motor will apply a steady torque to the load hence the name . a torque motor that cannot perform a complete rotation is known as a limited angle torque motor.
the torque and gear ratios are verifiable but your opinions about them aren't. isn't it enough to let the reader form their own opinion? what's wrong with mentioning that the torque rating for this car is unusually low? i could also mention that the torque curve is unusually steep. --spinynorman 19:26, 23 may 2006 utc steep, compared to what .
a wankel rotary engine is still a four-cycle engine, and pumping losses from non-power strokes still apply, but the absence of throttling valves and a 50% longer stroke duration result in a significantly lower pumping loss compared to a four-stroke reciprocating piston engine. measuring a wankel rotary engine in this way more accurately .
korndorfer starter with motor m , autotransformer at and three switches 1, 2, 3 in electrical engineering, the korndorfer starter is a technique used for reduced voltage soft starting of induction motors.the circuit uses a three-phase autotransformer and three three-phase switches. this motor starting method has been updated and improved by hilton raymond bacon.
an ac motor is an electric motor driven by an alternating current ac . the ac motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field.
the universal motor is a type of electric motor that can operate on either ac or dc power and uses an electromagnet as its stator to create its magnetic field. it is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator.it is often referred to as an ac series motor. the universal motor is very similar to a dc series .
one can measure the varying torque output over that range with a dynamometer, and show it as a torque curve. steam engines and electric motors tend to produce maximum torque close to zero rpm, with the torque diminishing as rotational speed rises due to increasing friction and other constraints .
the operating point of a system is the intersection point of the torque-speed curve of drive and machine. both devices are linked with a shaft so the speed is always identical. the drive creates the torque which rotates both devices. the machine creates the counter-torque, e.g. by being a moved device which needs permanent energy or a wheel .
