Product Description:

The P60B18750AXS25 is a brushless servo motor produced by Sanyo Denki for the P6 Super BL Servo Motors series. Its brushless electromagnetic design eliminates commutator wear, while the 180 mm square flange allows the unit to bolt directly to heavy gearboxes and frame plates. Because it is supplied without a holding brake, the axis must rely on an external locking mechanism when power is removed. Within automated cells, the P6 motor converts electrical energy from a drive amplifier into tightly regulated rotary motion for material-handling, packaging, and general positioning tasks.

At the rated operating point, the shaft delivers 7.5 kW at a speed of 1,500 rpm, generating 48.0 N·m of torque while the inverter supplies 58 Arms. For continuous static loading, the electromagnetic circuit sustains a torque of 54.9 N·m, assisted by a low phase resistance of 0.014 Ω and a torque constant of 0.90 N·m/Arms. Current rises to its commanded value within the 26 ms electrical time constant, allowing the windings to respond predictably to changes in the drive output. Rotor speed responds within the 0.49 ms mechanical time constant, which supports rapid speed adjustments during positioning cycles. A back-EMF gradient of 31.6 mV/min⁻¹ guides voltage prediction, while the 243 kW/s power rate indicates the motor’s ability to exchange energy during rapid acceleration and deceleration.

During short-term overloads, the winding can produce a maximum stall torque of 118 N·m and reach a top speed of 2,500 rpm. Thermal stability under these conditions is maintained by a frame-mounted cooling fan that draws 65 W. The drive sees a rotor inertia of 95.1 × 10⁻⁴ kg·m², which supports fast reversals without excessive overshoot. Position feedback is generated by a wiring-saving incremental encoder that reduces the connector count and simplifies cable routing in the control cabinet. The feedback signal allows the connected servo drive to monitor shaft movement and correct position or speed errors during operation.
