Product Description:
The PMB31D-10101-03 servo motor has a peak power of 6.1 Nm and can manage a current of 15.3 A_RMS. This motor is small and only weighs 2.5 kg altogether. When working within certain limits, the motor keeps working smoothly.
The PMB31D-10101-03 is a brushless servo motor for industrial automation, and it is manufactured by Pacific Scientific. A The constant torque at a stall current of 5.1 A_RMS is 2.03 Nm. The force continues at 0.40 N·m/A_RMS, whereas the voltage stays at 0.25 V_RMS/rad/s. It has a rated speed of 6,550 rpm and a torque of 1.53 Nm. The motor's operating resistance is 2 ohms, while its inductance is 4.2 MH. The rotor's inertia of 0.137 kg·m²×10⁻³ allows for a gradual increase in speed. The speed at which the motor responds to thermal stressors is determined by the thermal time constant, which is precisely 28 minutes. Thermal resistance (1.1 °C/W) affects the heat loss rate. The viscous damping value is 0.0124 Nm/krpm, which alters the torque losses associated with speed. During startup, static friction of 0.09 Nm must be overcome. The motor is employed in regulated situations where torque and thermal efficiency must remain consistent. The motor is utilized in regulated settings where uniformity in torque and thermal efficiency are paramount.
At zero speed, the PMB31D-10101-03 servo motor needs a minimum force of 0.09 Nm because of its static friction. The 2.5 kg total weight changes how the load is designed and mounted. The servo motor is designed for systems that need to control torque reliably and know how it will react to changes in temperature. It can be connected to industrial automation tools that put a high value on operational accuracy and thermal stability.
