Product Description:
The P50B08050DBS31 is an AC servo motor developed by Sanyo Denki as part of its P5 BL super servo motors series. It has a combination of speed and torque to support dynamic motion. The P50B0 servo motor is compatible with Sanyo Denki’s PY2 series servo amplifiers to enable high-speed industrial automation, CNC and robotics systems.
The P50B08050DBS31 super servo motor features a built-in 90 VDC electromagnetic holding brake that provides a torque of 1.96 Nm. The brake is designed to maintain axis position when power is removed and useful in vertical or load-holding applications. The P50B0 servo motor uses a factory-integrated incremental encoder with a resolution of 2000 pulses per revolution to provide closed-loop feedback essential for precise speed and position. Its rated power is 500 watts and operates at a speed of 3000 RPM. The P50B0 servo motor’s rated torque is 1.59 Nm and it can achieve a peak torque of up to 5.88 Nm during acceleration or sudden load changes. It operates on a 200 VAC three-phase power supply and draws 3.9 A during rated load conditions and supports peak currents up to 15 A. It has IP55-rated housing for protection against dust and water jets. The P50B0 servo motor achieves mounting via a standard 80 mm square flange with four M5 tapped holes.
The P50B08050DBS31 super servo motor supports a wide ambient temperature range from 0°C to 40°C and a storage range from –20°C to +65°C. It can be installed up to 1000 meters in elevation and operates reliably in environments with up to 90% relative humidity. The P50B0 servo motor includes an oil seal on the shaft for ingress protection while the shaft is 16 mm in diameter and 30 mm long. It features a machined keyway for secure coupling.
Frequently Asked Questions about P50B08050DBS31:
Q: Why does the P50B08050DBS31 use an incremental encoder instead of an absolute encoder?
A: Incremental encoders like the one in this model offer cost-effective closed-loop feedback and fast response times. They're ideal for systems where absolute positioning on power-up isn't critical.
Q: How does the 2000 PPR encoder benefit motion control in the P50B08050DBS31?
A: It enhances position accuracy and supports smoother velocity profiles. This is critical for synchronized multi-axis control systems.
Q: Why is the electromagnetic brake set at 90 VDC on the P50B08050DBS31?
A: The 90 VDC brake design ensures quick engagement/disengagement and reduced holding current. It’s optimized for power-off holding without excessive energy consumption.
Q: What role does the 3.9 A rated current play in system efficiency?
A: It enables sustained power delivery during standard operations. This balance supports both thermal stability and consistent performance.
Q: Why is an oil seal used on the shaft of the P50B08050DBS31?
A: The shaft oil seal prevents lubricant leaks and guards internal components from contamination. It also maintains smooth shaft rotation over time.
