Product Description:
The PBM603FXE20 is a brushless AC servo motor manufactured by Sanyo Denki for the PB SANMOTION Servo Motors series. Intended for closed-loop motion control, the model converts drive current into precise torque and speed for compact automation axes that require consistent repeatability. Its compact construction allows the motor to fit in limited spaces on semiconductor handlers, small gantries, and packaging machinery where fast response and accurate positioning are required. The motor works with a compatible servo amplifier that regulates output according to feedback from the connected axis.
Position feedback is generated by an optical incremental encoder that supplies a resolution of 2000 P/R to the amplifier. This resolution determines the minimum positional increment that the control system can detect at the motor shaft. At full excitation, the rotor can deliver 1.3 N·m of stall torque for holding the connected load without rotation. The 60 mm square frame limits the motor width while leaving room for stator windings suited to medium-power applications. Dynamic response is aided by a rotor inertia of 0.4 × 10⁻⁴ kg·m², allowing the motor to respond quickly to acceleration commands with limited overshoot. Mechanical coupling is handled through an 8 mm diameter shaft that extends 12 mm beyond the front face and accommodates suitable couplings or pulleys. A Z-phase output provides a once-per-revolution index for homing routines and reference position detection.
The front flange supports a radial load of 167 N at the designated measurement point and a thrust load of 14.7 N. These load capacities permit belt tension or moderate axial preload without placing excessive force on the bearings. The motor has an overall depth of 70.3 mm, which helps reduce the space required behind the mounting surface. Its mass is 0.85 kg, limiting cantilever loading on lightweight machine frames and moving assemblies. Four mounting holes arranged on a 49.5 mm pitch accept M4 × 0.7 screws for attachment to the machine structure. A 24 mm pilot recess centers the motor on the mounting surface to support accurate shaft alignment. The shaft keyway area has a minimum tapping depth of 8 mm for securing a compatible custom adapter.
