Panasonic Panasonic MBDHT2510E price MBDHT2510E service providers MBDHT2510E MBDHT2510E Panasonic motor power should be based on power production machinery needed to choose, try to make the motor run at rated load. Zhang Gong 182 019 88 309 QQ 8788 56 087 motor power size choice should pay attention to the following points: (1> if the motor power selected too small will be "small horse cart" phenomenon, resulting in motor overload so long. damage due to heat insulation and even the motor is burned. (2) If the motor power selected too large. there will be "big horse car" phenomenon. Its output mechanical power can not be fully utilized, power factor and efficiency is not high not only detrimental to the user and the grid will result in energy waste and to correctly select the motor power, must go through the following calculations or comparisons: (1) For a constant load of continuous work, if you know the power of the load (ie, the production of mechanical axis . The power) Pl (kw) motor power required can be calculated as P (kw): P = P1 / n1n2 where n1 is the efficiency of production machinery; n2 for the efficiency of the motor that drives efficiency by the above formula. obtained power, not necessarily the same as the product of power and therefore the selected nominal motor power should be equal to or slightly greater than the calculated power Example:.... a production machinery power 3.95kw mechanical efficiency of 70%, if the choice of motor efficiency is 0.8, find the number of kw motor power solution should be: P = P1 / n1n2 = 3.95 / 0.7 * 0.8 = 7.1kw 7.1kw this because there is no - so use 7.5kw's specifications?. motor. (2) short-time work quota motors. Compared with the same continuous power motor fixed maximum torque, low weight, low price. Therefore, when conditions permit, you should try to use short-time work quota motor. (3) For intermittent operation of a motor fixed, the power of choice, according to the duty cycle of the size, the choice of motor designed for intermittent operation mode. load continuous string formulas Fs% of FS% = tg / (tg + to) × 100% where tg as working time, t stop time min;. tg ten min cycle time to work analogy can also be used in addition to select the motor power is with the so-called analogy.... similar machinery used in the production of motor power to compare specific approach is: Learn the unit or other units nearby similar production machinery use more powerful motors, and then choose the similar power motor test test purpose is to verify that the selected motor and production. Mechanical match validated methods are: production of motor driven mechanical operation, measuring motor current clamp meter with the measured current and on the motor nameplate rated current to compare the actual machine if the electric power operating current and rated current up and down on the Ming spleen or less marked. it indicates the selected motor power is appropriate. If the actual operating current of the motor nameplate than the rated current of about 70% lower. it means that the motor power option too large (ie, the "big horse car" should be reversed smaller power motor. If the measured ratio of the motor operating current marked on the nameplate rated current of more than 40%. It indicates that the motor power selected too small (ie, "small horse cart"), should be reversed larger power motors.
