Product Description:
The P50B05005DCSA7M is a compact brushless servo motor built by Sanyo Denki within the P5 Super BL Servo Motors series. Designed for light-duty axes in conveyors, indexers, and laboratory instruments, it converts drive current into controlled rotary motion while an integral holding brake locks the shaft when power is removed. Its wiring-saved incremental encoder returns position data to the drive, allowing the closed-loop controller to maintain accuracy during rapid direction changes in general industrial automation.
The motor mounts on a square flange that measures 54 mm across and delivers a continuous mechanical output of 50 W. Under rated operating conditions, the rotor turns at 3,000 rpm and produces a continuous torque of 0.159 N·m, drawing 0.85 Arms through 9.2 Ω phase windings. When commanded to accelerate, the drive can increase the operating frequency until the rotor reaches 4,500 rpm, a ceiling that protects the magnets and bearings from excessive mechanical stress. The torque constant is 0.249 N·m/Arms, allowing the controller to calculate the current required for changes in mechanical load. Position feedback is generated by a 2,000-pulse-per-revolution encoder, which provides the drive with the data needed for precise speed and position regulation. CE and UL certifications facilitate the motor’s use in industrial control cabinets for different markets.
During holding and peak-load events, the motor supplies 0.167 N·m of continuous stall torque and can withstand up to 0.49 N·m briefly before reaching its thermal limits. A static electromagnetic brake operates at 24 V and 0.26 A to clamp the shaft when motor power is unavailable. Surge demand can reach 2.9 Arms, which is the maximum stall current that the connected drive must be able to supply. Dynamic response is supported by a rotor inertia of 0.063 × 10⁻⁴ kg·m², helping the motor accelerate and decelerate rapidly in positioning applications. The electrical time constant is 2.1 ms, enabling a rapid current rise and precise velocity regulation during short motion cycles.
