【正文】 ect current source on the contrary straight end GND negative end A direct current source receive generator draw forth line red line receive generator draw forth line green line B receive generator draw forth line yellow line receive generator draw forth line blue line step enter generator as soon as finalize the design , its performance depend on the drive of generator power source. The more walk into generator rotational speed to be high, the more force distance the current that asks generator the more big, drive the voltage of power source is high the more. Voltage is as follows for moment influence: 4 divide into actuator carefully In the condition that step can not satisfy use into the generator angle of step pitch take off, can adopt thin minute actuator e to drive step enter generator, the principle that divides into actuator carefully is to be adjacent through changing (A, B ) the size of current, with the included angle that changes synthetic magic field control step operates into generator. 2, the application that walks into generator (one) walk into the option of generator to walk into generator, have the angle of step pitch (is concerned with appearance number), quiet torque, and 3 current gist plain in color positions. Once 3 gist vegetarian meals determine, step determines into the model of generator. 1 the step pitch of the angle of step pitch that selects generator angle depend on the requirement of load precision, go to the minimum( equivalent) conversion of resolution capacity of load on generator axle, every equivalent generator should go to how many angle ( include deceleration ). The angle of step pitch of generator should be equal to or be smaller than this angle. Now on market, step has the degree degrees of / ( 5 appearance generator ) normally into the angle of step pitch of generator , the degree degrees of / ( 2 and 4 appearance generator ) , degree / 3 degree( threephase generator) etc.. Step is nearly impossible to determine the option of 2 moments right off into the development moment of generator, we often determine the quiet moment of generator first. The basis of quiet moment option is the load of generator work, and load can divide into inertia load with friction load 2 kinds. Unitary inertia load and unitary friction load do not exist. When directly starting (general from low speed) 2 kinds of load will consider, when acceleration starts, considers inertia load mainly, the operation of constant speed enter consider friction load only. Usually quiet moment should be friction load 23 time good, quiet moment once choose , length and the baseplate of generator can determine ( geometry size ) the option of 3 currents the generator as quiet moment, since current parameter is different, its operation property difference is great , can judge the current( reference drive power source , and driving voltage) 4 of generator according to rules frequently property curve map moment and power conversion step enter generator the general speed adjustment in greater scope use and its power is change, make efforts normally only rules e to measure, moment and power conversion are as follows: P= ΩM Ω=2πn/60 P=2πnM/60 P is power unit is tile, Ω is each second of angular velocity, unit is radian, n is each minute of rotational speed, is M Newton for moment unit Metre P = 2 π fM/400 ( half step work ) in which f is each second of pulse number ( abbreviation PPS ) ( 2 ) , step and the notice a little 1 in application enter generator application in the occasion of low speed each minute of rotational speed do not exceed 1000 turn , ( degrees 6666 PPS ), best in 10003000 PPS ( degrees ) between use, but pass through deceleration installation make it in here work, right now, generator working efficiency has low noise high. 2 walk into generator had better not use synchronization state, synchronization state vibration big. 3 because of historical reason have only nominal is the generator of the voltage of 12 V use 12 V besides, the voltage value of other generators does not be that driving voltage bends over value, can select driving voltage according to actua tor ( suggestion: 57 BYG adopts 24 V36 V of direct current, 86 BYG adopt 50 V,110 BYG of direct current adopting is higher than the 80 V of direct current), certainly 12 the voltage that bends exclude the drive of 12 V of constant voltage besides can also adopt other drives power source, however, will consider temperature rise. 4 turn the load of big inertia should select baseplate generator. 5, generator is being higher and fast or inertia load , normally not in working speed start , and with gradually litre frequency mention fast, a generator do not lose step, 2 can reduce noise, can at the same time raise the positional accuracy that stops. 6 high accuracy , should solve through the mechanical actuator that slows down and raises generator speed or adopts high thin grade , can also adopt 5 appearance generator, however, the price of its entire system is lost than your, manufacturer home, it is lay language by the saying of elimination. 7, generator should not work in vibration district, as if must can pass through the solution that changes voltage and current or adds some damping. 8 generator in 600 PPS ( degrees) with go off work make , should drive with little current, big inductance and low voltage. 9 should follow choose the principle of choosing drive after generator first.
