Abstract
The first electric motor, the homopolar motor, was demonstrated by Michael Faraday in 1821 at the Royal Institution of London. The homopolar motor operates on the principle that a force is produced orthogonal to current and magnetic field. The Homopolar Racer Competition (HRC) is a college-level competition created to raise awareness and interest in electromagnetic launcher technology and research and to serve as a multi-disciplinary training tool in this area. Student teams design, build, and demonstrate a homopolar motor in the form of a vehicle (i.e., the racer) that rolls along the ground. The students learn electrical, mechanical, and chemical engineering concepts along with principles from physics and material science. The racer must carry its own battery power during the race. Battery weight cannot exceed 100 grams. Scoring is based on the shortest time to travel the 10 meter track. This investigation will focus on HRC operation and design along with the rules of the event. The investigation will also report the results from the 2008 HRC event at the University of Missouri. The winning racer of that event achieved velocities of 2.4 m/s over the 10-meter track using a single battery.
1821年,迈克尔·法拉第(Michael Faraday)在伦敦皇家学院(Royal Institution of London)演示了第一台电动机——同极电动机。同极电动机的工作原理是产生与电流和磁场正交的力。同极赛车比赛(HRC)是一项大学水平的比赛,旨在提高人们对电磁发射器技术和研究的认识和兴趣,并作为该领域的多学科培训工具。学生团队设计、建造并演示一个在地面上滚动的车辆(即赛车)形式的同极电机。学生学习电气、机械和化学工程概念以及物理和材料科学原理。参赛者必须在比赛中携带自己的电池。电池重量不能超过100g。得分是基于最短时间走完10米的轨道。本次调查将重点关注HRC的运作和设计以及赛事规则。调查还将报告2008年在密苏里大学举行的人权委员会活动的结果。该赛事的冠军选手在10米赛道上使用一块电池的速度达到了2.4米/秒。
