According to different environment, the utility model can change to corresponding size, to meet the demand under various behaviours in service.Below provide motor type selection calculation process of the present utility model.
Most important two parameters of motor are motor torque and motor power.Motor torque M (Nm)=9550 * motor power P (kW)/motor rotary speed (r/min).
Motor torque acting A=(motor torque M * motor angular velocity of rotation w * moment application time t)/2.
Load rotational kinetic energy E=(load rotating inertia summation J * load angular velocity of rotation w * load angular velocity of rotation w)/2.
Under desirable state, when motor torque acting A=load rotational kinetic energy E, the torque and the power that can be considered motor have all reached requirement, now can release motor torque M=load rotating inertia summation J * load angular velocity of rotation w/ moment application time t.But this formula has a restrictive condition, and after needing to set load being applied to torque M, the angular velocity of load is by the 0 time t that accelerates to angular velocity w.In order to guarantee the fluency of picture disply, we are set as 1 second by time t.
Load rotating inertia summation J equals each load rotating inertia sum, that is:
J=J shaft coupling+J rotation axis+J slip ring+J coupling shaft+J swivel arm+J display device bracing frame+JLED lamppost+J lamppost control panel+J power board+J connection cable
The moment of inertia that the moment of inertia of each parts provides with producer is as the criterion.
The display frame frame frequency of take calculates as 30 frames, equipment rotational speed n=30/8=3.75 (r/sec)=225 (r/min).
Angular velocity of rotation w=n * 2 π=23.562rad/s.(π gets 3.1416)
Moment application time t is set as 1 second.
Can calculate motor torque M according to top three amounts, then calculate motor power P according to M=9550P/n.
Consider screw, nut, moment of friction and other influences factor, when calculating motor torque M, can reserve 20% affluence.
According to above calculating, can calculate motor torque and power, we can be according to different environment, no demand, different lamppost quantity is adjusted torque and the power of motor, to reach equipment requirement.
The utility model utilizes the persistence of vision principle, and the fractionation of view picture picture is in column, and the LED lamppost is scanned by column, and when the LED lamppost rotates, can see still image and dynamic menu.The demonstration of multiple row lamppost synchronous rotary has formed a complete dynamic menu.
