Product Description:
The PMB31D-10101-02 brushless servo motor is made by Pacific Scientific and is built for precise control jobs. The motor is rated to go at 6,550 rpm and has a torque of 1.53 Nm. It is used in automated systems that need a steady level of power and accurate speed management. The motor is 2.5 kg and has a small size that makes it easy to integrate.
The resistance of the PMB31D-10101-02 brushless servo motor is 2 ohms, and its inductance is 4.2 mH. These numbers show how well it uses electricity. The factors for converting electricity to mechanical energy are 0.40 N·m/A_RMS for the torque and 0.25 V_RMS/rad/s for the voltage. The constant stall torque is 2.03 Nm, which ensures that the torque stays the same at zero speed. At peak power, the motor needs 15.3 A_RMS of current, and at stall, it needs 5.1 A_RMS. Short bursts of work are possible with its top torque of 6.1 Nm. It has an inertia of 0.137 kg·m²×10⁻³, which helps it move quickly, speed up, or slow down. The motor's starting process is influenced by the static drag, which is 0.09 Nm. Its thermal resistance is 1.1 °C/W, which lets the heat escape while it is working. It is used in factory automation applications that require precision control and consistent thermal performance.
The PMB31D-10101-02 brushless servo motor has a thermal time constant of 28 minutes, which shows how the motor reacts to changes in temperature. The resistance to rotational speed is given by the viscous damping coefficient, which is 0.0124 Nm/krpm. The product can consistently provide torque and manage heat effectively. The brushless servo motor can be used in control systems that need accurate input and motion control.
Frequently Asked Questions about PMB31D-10101-02:
Q: Does PMB31D-10101-02 support high-speed operation reliably?
A: Yes, the PMB31D-10101-02 operates at 6,550 rpm typical rated speed. It supports rapid acceleration without compromising control and thermal limits.
Q: Why is the inductance of PMB31D-10101-02 rated at 4.2 mH?
A: The 4.2 mH inductance helps in smoothing the current response. It reduces torque ripple and ensures controlled motor behavior in feedback-driven systems.
Q: How does PMB31D-10101-02 manage thermal dissipation efficiently?
A: The motor has a thermal resistance of 1.1 °C/W. This promotes heat dissipation and keeps winding temperatures within safe limits during prolonged duty.
Q: Do static friction levels in PMB31D-10101-02 affect startup?
A: Yes, the 0.09 Nm static friction defines the initial breakaway torque. It allows smoother and more controlled motor starts in load-sensitive conditions.
Q: Why does PMB31D-10101-02 need 15.3 A_RMS for peak torque?
A: The motor requires 15.3 A_RMS to achieve 6.1 Nm peak torque. This ensures short-term overload capacity for handling rapid load changes.
