Product Description:
The P20B10150DCPU3 model is identified as a servo motor which is developed by Sanyo Denki. It is designed specifically to use in tasks that promote industrial automation.
The P20B10150DCPU3 servo motor can withstand peak torque up to 14.7 Nm for a short duration without damage. It can deliver continuous torque of 4.79 newton meters during standard operation without overheating. It can hold 4.90 newton torque at zero speed (stall) indefinitely without exceeding thermal limits. The current in the motor winding builds up in 13 msec. The RMS current required to generate the rated torque under continuous load is 8.4 arms. It features a 24 volts holding brake to maintain position when power is removed. The rotor's resistance to acceleration or deceleration is shown by 2.04 × 10⁻⁴ kgm² inertia which affects motion smoothness and control loop tuning. The amount of torque produced per ampere of current is 0.65 newton meter. The highest speed it is able to achieve is 4500 rpm without risking mechanical or electrical failure. It uses an absolute encoder ABS-RII which provides precise position feedback with power off memory. It has a back EMC constant value of 22.6 V/krpm which defines the voltage generated per 1000 rpm.
The P2 Super BL Servo Motors series module has a continuous stall current of 8.1 arms. The peak armature current it can handle momentarily at stall for high torque demands is 26.5 arms. Its single phase has an electrical resistance of 0.42 ohm which affects power loss and thermal characteristics. It requires 0.59 msec to reach its speed to 63.2% of its final value after a step torque is applied.
Frequently Asked Questions about P20B10150DCPU3:
Q: How does the 100 mm flange size benefit in machine installation flexibility?
A: The 100 mm flange size standardizes mounting and simplifies motor replacement in existing systems. It ensures easy mechanical integration in industrial setups.
Q: Why is ABS-RII encoder important in the P20B10150DCPU3 servo motor?
A: The ABS-RII encoder provides absolute position feedback even after power loss. This enhances repeatability and positioning accuracy in automation cycles.
Q: What is the significance of 22.6 V/krpm back EMF in P20B10150DCPU3?
A: It helps in matching the motor with suitable drives based on voltage generation. This ensures efficient energy conversion during high-speed operation.
Q: How does the 0.42 Ω phase resistance affect motor performance?
A: Lower resistance reduces I²R losses, improving thermal efficiency and current handling. It contributes to better overall motor performance and longevity.
Q: What does 13 msec electrical time constant indicate for P20B10150DCPU3?
A: It reflects the motor’s ability to react to electrical signal changes. Faster electrical response leads to quicker torque adjustments during motion.
