Product Description:

The PBM603FXK30-M is a compact AC servo motor produced by Sanyo Denki within the PB SANMOTION Servo Motors series. Designed for positioning and speed-regulated axes in industrial automation, the unit converts drive current into controlled rotary motion that can be monitored by a servo amplifier for closed-loop control. Its compact dimensions and built-in encoder make it suitable for pick-and-place stations, small gantries, and other equipment that requires repeatable motion. The motor can support applications in which accurate acceleration, deceleration, and positioning are required within a limited installation space.

At the output side, the motor can develop a maximum stall torque of 1.3 N·m, allowing it to hold position against static loads during closed-loop operation. Position feedback is provided by an incremental encoder with a resolution of 16,000 pulses per revolution, enabling fine command increments when used with a compatible drive. The square mounting face follows a 60 mm flange standard, while a pilot diameter of 36 mm centers the housing on the machine plate. A single D-shaped shaft measures 10 mm in diameter, providing positive engagement with a matching hub. Dynamic response is supported by a low rotor inertia of 0.4 × 10⁻⁴ kg·m². The enclosure has an IP40 protection rating, so it resists solid particles larger than 1 mm in typical cabinet installations. Power and signal conductors use AWG 22 lead wires terminated in a molded connector, providing a secure electrical connection.

The bearing system permits a continuous radial load of 190 N and an axial thrust of 14.7 N. These load capacities accommodate moderate belt tension and gearbox end play without placing excessive force on the bearings. With a total length of 68.8 mm, the frame helps keep machine depth limited in compact installations. The motor weighs 0.85 kg, reducing the added mass carried by moving machine assemblies. Its low mass is particularly useful when the motor is installed on a carriage or gantry that must accelerate and change direction repeatedly.
