Product Description:

The P30B04005PCKST is a compact servo motor and gearhead assembly from Sanyo Denki’s P3 Super BL Servo Motors series. Built with brushless motor technology, the unit integrates a precision planetary reducer with a 1/10 reduction ratio and an internal holding brake. The brake allows the motor to retain its position when power is removed, making the assembly suitable for axes that must remain stationary during shutdowns or emergency stops. An IP40 protection system shields the frame from contact with larger solid objects. The Class F insulation system supports the winding temperatures associated with continuous motor operation. Its compact design is suitable for light-duty pick-and-place axes, indexing mechanisms, and small fixture actuators in automated equipment.

The holding brake operates with a supply of 24 V and draws 0.26 A to provide static shaft locking. Position feedback is supplied by a 2,000 P/R incremental encoder, giving the drive controller detailed information about rotor movement. This encoder provides 0.18 degrees of resolution per pulse for position and speed regulation. Mounting uses a 40 or 42 mm square flange pattern, allowing the assembly to fit compact stages with either supported flange size. Helical gears inside the reducer provide 90% mechanical efficiency and help transmit torque with smooth engagement. The reducer supplies a continuous shaft output torque of 1.4 N·m. Its gear face measures 60 × 60 mm, providing a stable mounting surface within a small mechanical footprint. The nominal reducer output speed is limited to 300 rpm, which supports controlled movement at the load while reducing the effect of motor torque ripple.

The motor windings withstand a dielectric voltage of 1,500 VAC between the phases and frame, providing insulation between energized conductors and the housing. Backlash at the reducer output is limited to 90 arcmin, making the assembly appropriate for indexing conveyors and positioning tasks that do not require sub-arc-minute accuracy. The brushless rotor can reach a maximum speed of 4,500 rpm, supporting rapid motor response before the reducer lowers the speed delivered to the load. The motor has a rated output of 50 W, which suits compact mechanisms with moderate power requirements. Brushless commutation reduces mechanical wear because the rotor does not rely on carbon brushes to switch current. The planetary reducer distributes transmitted load across multiple gear contacts, while the helical tooth form promotes quieter and smoother operation than a comparable straight-cut arrangement.
