2013-08-09 20:03Stepper motor selection

Should follow the first election after the election motor drive principle, first explicitly load characteristics, and then by comparing the different models and static torque stepper motor torque-frequency curve to find the best match with the load characteristics of stepper motor; precision is high, should be mechanical deceleration devices, so that the motor operates at the highest efficiency, lowest noise of the state; avoid working in the vibration of the motor area, should have it by changing the voltage, current, or increase the damping solutions; supply voltage, the proposed 57 motor with DC 24V-36V, 86 motor with DC 46V, 110 motor is higher than the DC 80V; big inertia load should choose a larger frame size motors; large inertia loads, high operating speed, the motor and the frequency should be used to gradually speed up to prevent the motor out of step, to reduce noise, improve the positioning accuracy when stalled; view of the stepper motor torque 40Nm less generally beyond the scope of this moment, and the running speed is greater than 1000RPM, that should be considered when selecting servo motors, AC servo motors can generally normal operation at 3000RPM, DC servo motor functioning in cocoa 10000RPM.
