6 Roosevelti tugev poolehoid Ühendriikide kõik rahvastatumas osariigis tegid temast kindla demokraatilise partei kandidaadi presidendi valimisteks. Tema vastane Herbert Hoover oli kergelt haavatav, Al Smithi toetasid ainult mõned linna bossid. Roosevelt ehitas üles oma enda rahvusliku koalitsiooni, oma isikliku liidu, mis koosnes ajalehe magnaadist William Randolph Hearstist, Iiri juhist Joseph P. Kennedyst ja California juhist William Gibbs McAdoost, kui ka Texase just John Nance Garner astus üle Roosevelti pooldajaks, siis sellega teenis ta asepresidendiks kandideerimise koha. 1932. Aastal valitigi Roosevelt esimest korda Ameerika Ühendriikide presidendiks. ,,Uus kurss" lühim tee Valgesse Majja 1930/31 aasta külmal kriisitalvel muutus olukord riigis meeleheitlikuks: töötute hulk lähenes kümnele miljonile ja igaühel neist oli perekond, mis tegi ühtekokku mitukümmend miljonit vaest inimest
finally stops. Figure 7.5 illustrates this. The frequency at which the rotor oscil- lates depends on the motor characteristics (rotor mass and construction, for instance) and the load. If the motor is connected to a load that looks like a flywheel (a mechanical shutter in an optical system, for example), resonance may be more of a problem than an unloaded motor. A load with a lot of fric- tion, such as a belt-driven pulley, has a damping effect that will reduce reso- nance (unless the belt is connected to a flywheel). Many stepper motors exhibit a sudden loss of torque when operating at certain step rates. This occurs when the step rate coincides with the oscilla- tion frequency of the rotor. The torque can change enough to cause missed steps and loss of synchronization. There may be more than one band of step rates that cause this effect (because the motor has more than one resonant frequency). In a design that only uses one step rate, these frequency bands
• Allow at least 200 mm between the CPM1A and nearby power lines. 200 mm min. CPM1A 200 mm min. Accessibility Ensure that the CPM1A can be accessed for normal operation and mainte- nance. • Provide a clear path to the CPM1A for operation and maintenance. High-volt- age equipment or power lines could be dangerous if they are in the way during routine operations. • The PC will be easiest to access if the panel or cabinet is installed about 3 to 5 feet off of the floor. 44
