PY0A300W4PW1A00

The PY0A300W4PW1A00 servo amplifier from Sanyo Denki is part of the PY Super BL Servo Amplifiers series, designed for industrial automation requiring high-output performance. It delivers a Rated Output of 4500 W at a nominal Rated Revolution Speed of 2000 min−1, while supporting peak operation up to Maximum Revolution Speed of 2500 min−1. The amplifier weighs 22.0 kg, including wiring-saved components, ensuring a robust construction. With a Torque Constant of 1.05 N·m/Arms and an Induced Voltage Constant of 36.7 mV/min−1, it provides a balanced combination of power density and precise control. It is engineered for high-demand industrial automation tasks requiring reliable motion control.

The amplifier sustains a Continuous Stall Armature Current of 31.6 Arms and achieves an Instantaneous Maximum Stall Armature Current of 79.7 Arms for exceptional transient response. It provides a constant Continuous Stall Torque of 32.0 N·m and can counteract load spikes with an Instantaneous Maximum Stall Torque of 70.0 N·m. The low Phase Armature Resistance of 0.043 Ω minimizes thermal losses and enhances efficiency under heavy loads. Its electrical dynamics are optimized by an Electrical Time Constant of 33 msec, facilitating rapid current response. The inherent design leverages these electrical parameters to maintain stable performance in demanding environments.

With a Mechanical Time Constant of 0.68 msec, the amplifier ensures swift mechanical response and tight speed regulation. A Rated Armature Current of 24.1 Arms and a nominal Rated Torque of 21.5 N·m enable sustained operation under varied load profiles. The design’s high-power density supports smooth acceleration and deceleration cycles, reducing overshoot and vibration. Additionally, the robust thermal management inherent to the construction guarantees consistent output during extended duty cycles.

The compact form factor and standardized interfaces allow seamless integration with a wide range of servo motors and controller systems. This versatile amplifier is well suited for CNC machining centers, robotic automation, packaging lines, and other industrial applications demanding high precision and reliability. Engineers will benefit from its scalability within automated installations and its compatibility with existing industrial drive architectures. It also supports advanced feedback loops and protective functions for integrated safety compliance.
