Product Description:

The P10B10120HCSB8 is a brushless AC servo motor produced by Sanyo Denki for the P1 Super BL Servo Motors series. The motor uses permanent-magnet excitation to generate controlled torque and speed for automated pick-and-place axes, gantry drives, and machine tool heads. It mounts through a flange interface and includes a wiring-saving incremental encoder that transmits position data to the drive through fewer feedback conductors. An integrated holding brake secures the shaft at rest, allowing vertical loads to remain stationary when motor power is removed.

The flange measures 100 mm across, providing a standardized mounting face for compatible gearboxes and machine frames. Rotor speed reaches 3000 rpm, accommodating common servo drive outputs while keeping centrifugal forces within the motor’s operating limits. The encoder provides 6,000 P/R, dividing each revolution into fine increments that support accurate position and speed control. The brake operates from a 24 V DC supply provided by the control system. The winding insulation has a dielectric strength of 1,500 VAC for 1 minute, helping keep the phase conductors electrically isolated from the motor housing during abnormal voltage conditions.

The windings use Class F insulation, which provides thermal resistance suitable for continuous industrial operation. Insulation resistance to ground remains above 10 MΩ at 500 V DC, indicating low leakage between the energized windings and grounded housing. The motor has a fully enclosed, self-cooling housing, allowing heat to dissipate without a separate cooling fan. A shaft seal limits the entry of dust and coolant near the bearing and output shaft interface. Running balance conforms to the V10 vibration grade, helping reduce dynamic loads when the motor is directly coupled to precision mechanisms, while the brushless design reduces wear associated with mechanical commutation.
