PY0A050H0P26P00

The Sanyo Denki PY0A050H0P26P00 serves as a high-performance servo amplifier within the PY Super BL Servo Amplifiers lineup, engineered to deliver reliable power in demanding industrial automation environments. Manufactured by Sanyo Denki, this unit features a Rated Output of 4500 W coupled with a Rated Revolution Speed of 2000 rpm, providing robust control over motor-driven processes. With a substantial Weight of 22.0 kg and a compact footprint designed for standard cabinet mounting, the amplifier integrates seamlessly into factory control panels. The device also supports a Maximum Revolution Speed of 2500 rpm and a Torque Constant (kt) of 1.05 N•m/Arms, ensuring precise torque delivery across a wide speed range.

Technical excellence is evident in the amplifier’s electrical and mechanical specifications. The Continuous Stall Armature Current of 31.6 Arms and the Instantaneous Maximum Stall Armature Current of 79.7 Arms provide ample current headroom for peak torque demands. Its Continuous Stall Torque of 32.0 N•m and Instantaneous Maximum Stall Torque of 70.0 N•m ensure consistent mechanical output under heavy loads. The unit features a Phase Armature Resistance of 0.043 Ω and an Electrical Time Constant of 33 msec, optimizing transient response and stability. The Mechanical Time Constant of 0.68 msec and the Induced Voltage Constant (keφ) of 36.7 V/krpm further enhance dynamic performance and control accuracy.

Operational features of the PY0A050H0P26P00 focus on thermal management, current regulation, and energy recovery. Built-in cooling fins dissipate 85 W of power loss—30 W through the heatsink and 55 W through the PCB—maintaining optimal operating temperatures. The amplifier supports 12 AWG motor and bus wiring, minimizing conductor losses while carrying steady bus circuit currents between 8.7 A and 9.2 A. Regenerative braking returns up to 60 W of energy to the bus, improving system efficiency and reducing waste heat. Braking dynamics are adjustable via t₀ constants (0.0100 to 0.0240 s) and temperature coefficients α (2.19 to 2.99) and β (0.30 to 1.05), ensuring smooth deceleration and protection under varying load conditions.

Integration into modern automation systems is streamlined through the amplifier’s standard form factor and control interface compatibility. The PY0A050H0P26P00 pairs readily with industrial PLCs, motion controllers, and Sanyo Denki’s own feedback sensors, enabling closed-loop position and speed control. Its robust specification set makes it ideal for robotic arms, CNC machinery, conveyor drives, and other precision motion applications. Engineers will appreciate the balance of high torque density, fast response characteristics, and energy-saving regenerative functionality when deploying this amplifier in complex production environments.
