SX30A8 Analog Servo Drive Description Power Range The SX30A8 PWM servo drive is designed to drive three phase brushless motors with sine wave current at a high switching frequency. The drive requires two sinusoidal command signals with a 120-degree phase shift (external commutation). The phase angle must correspond to the position of the motor rotor, while the signal amplitude controls the motor torque. The SX30A8 interfaces directly with digital controllers. The drive is fully protected against over-voltage, overcurrent, over-heating, and short-circuits, and requires only a single unregulated DC power supply (all logic and control voltages are generated internally). A red/green LED and two digital outputs indicate operating status. 30 A (21.2 A RMS ) Peak Current Continuous Current Supply Voltage 15 A RMS 20 - 80 VDC See Part Numbering Information on last page of datasheet for additional ordering options.
