How do you select the power of the drive and drive
Driver selection: From the principle of stepping motor power is more abundant, the better, because the cost of production in the actual application needs of the user often under the condition of meet the requirements for power as small as possible. Power too low, the first is easy to cause the output torque of the motor to be insufficient or even to lose the step, the second is also easy to damage the drive and even switch the power supply. The specific power choices are closely related to the user's system requirements and system configuration. The power options: The voltage is 10% to 50% higher than the maximum required voltage. This percentage is different from Kt, Ke, and voltage drops in the system. The current value of the driver should be sufficient to transmit the energy required for the application. Remember that the output voltage of the actuator is different from the supply voltage, so the actuator output current is different from the input current. To determine the right supply current, you need to calculate all the power requirements for this application and increase by 5%. The desired value of the current can be obtained by calculating the I = P/V formula.
Stepper motor is usually a 24 v switching power supply, choose suitable best when buying drive current, current big words will burn machine, to be on the safe side, started the drive current first transferred to the minimum, then slowly adjust make motor run properly, avoid burning motor.
When choosing stepping drive power, motor in the process of the work should be considered the effects on the power supply voltage fluctuations, can't let work voltage more than the highest operating voltage of the drive. If the switch power supply, the choice of higher voltage can be appropriate, if using linear power supply transformer, voltage to choose lower) to consider the network voltage fluctuation. Such as Britain, shi EZM552, working voltage is 20 ~ 50 VDC, when choosing switch power supply, power supply voltage can be up to 40 VDC, if you want to work to 48 ~ 60 VDC voltage, you can choose EZM852, power of power can press 0.7 * * working current to estimate the working voltage.
The recommended voltage is 10% to 50% higher than the maximum required voltage. This percentage over Kt, Ke, and the voltage drop in the system is different. The current value of the driver should be sufficient to transmit the energy required for the application. Remember that the output voltage of the drive is different from the power supply voltage. So the output current of the driver is not the same as the input current. To determine the right supply current, you need to calculate all the power requirements for this application and increase by 5%. According to I = The P/V formula can be calculated to obtain the desired current value. From the principle of stepping motor power is more abundant, the better, because the cost of production in the actual application needs of the user often under the condition of meet the requirements for power as small as possible. Power too low, the first is easy to cause the output torque of the motor to be insufficient or even to lose the step, the second is also easy to damage the drive and even switch the power supply. The specific power choices are closely related to the user's system requirements and system configuration.
For the type of the step motor, it is mainly the power of the switch, the current is not less than the maximum current of the driver. Some type of step motor, for switching power, condition permitting, 24vdc-90vdc can choose large, not small. Some step-motor torque curves are tested by 80VDC voltage.
