I need to calculate the amount of torque required from the motors to be able to move the object of x kilograms consistently (without skipping any steps) at a velocity of y, travelling up a slope of angle z. I'm guessing this would also depend on factors like the grip of the tyre and such?

If you exert a force at some distance from the pivot point, then even though the force will act along a straight line, the object will begin to rotate. I can't figure out how to calculate the Force in this equation though, so that I may find the Torque. So you have 12/8 = 1.5 mechanical advantage at wheel. %PDF-1.4 Torque is a force tending to rotate a body about an axis. .top-header-menu li a:hover, The torque (tendency of an object to rotate) depends on three different factors: τ = rFsin(θ) where: r is the lever arm - the distance between the pivot point and the point of force application;; F is the force acting on the object;; θ is the angle between the force vector and lever arm. background-color: #ffffff; Determine the motion profile and calculate acceleration, deceleration and maximum velocity required to make the desired move. var td_magnific_popup_translation_tNext="Avan\u00e7ar (tecla de seta para a direita)"; Calculate rack and pinion: important definitions. .td_round_btn, .td_block_template_5 .td-block-title > *, .td-mega-span h3 a:hover, .td-footer-wrapper .td-excerpt, When studying how objects rotate, it quickly becomes necessary to figure out how a given force results in a change in the rotational motion. .tdm-menu-active-style4 .tdm-header .sf-menu > .sfHover > a { For rotational motion, the same force can cause very different results. wheel radius of drive wheel This torque can be obtained by directly mounting a motor with the torque value on the differential of the vehicle or by using a gearbox or chain drive to magnify a lesser torque to this value before it drives the wheel. Here’s an interesting fact about DVD players: They actually change […] Known variables: Weight (lbs), Linear Velocity (ft/min), Speed of Driving Motor (RPM), Change in Speed (RPM), and Time to Accelerate Total System (sec) In addition to the torque required to drive the load at a steady speed, torque is required to accelerate the load.

Example ): torque = force * radius ( of the platform at width/2 and have the torque: must. #bbpress-forums .bbp-body .super-sticky li.bbp-topic-title .bbp-topic-permalink, There is no torque opposing the torque due to the weight of the system, hence there is a net clockwise torque. } The resultant torque was calculated from the result of the acceleration due to gravity. If when the wheel is moving at a constant rate, and the torque then is zero as you say, then according motor principles the motor should stop spinning since torque is relative to speed. endstream endobj 217 0 obj <>/Size 201/Type/XRef>>stream m Total weight of work and table [oz.] In this tutorial, we are going to calculate the wheel torque and force for a given: engine torque; gear ratio (of the engaged gear) final drive ratio (at the differential) So even a very low torque motor can get a well balaced wheel system to rotate, its just going to take a long time to accelerate the system.
