Product Description:
The PMB33E-10100-03 Servo motor by Pacific Scientific is built for industrial automation control. It features a square mounting face with dimensions of 86 × 86 mm. The overall body length is approximately 177 mm. The shaft has a diameter of 12.7 mm and a length of about 32 mm. It has four mounting holes with a 7.1 mm width each.
The PMB33E-10100-03 servo motor has a total weight of 6.3 kg. The rotating mass of the rotor is 0.40 × 10⁻³ kg·m². This motor delivers a continuous holding torque of 5.4 Nm. Its typical operating torque is 4.4 Nm at a standard speed of 3,800 RPM. The maximum torque output reaches 11.0 Nm during short bursts. The torque-to-current ratio is 1.86 Nm per ampere. The voltage generated per speed unit is 0.57 V/krpm. The steady current draw is 2.9 A RMS, while the peak current can go up to 8.7 A RMS. The enclosure of the PMB33E-10100-03 servo motor is rated IP40. It protects the motor against solid objects larger than 1 mm. There is no protection against moisture or liquids. The motor operates within a temperature span of –20 °C to +40 °C. It can function in environments with humidity levels up to 95%, non-condensing. The heat is managed through passive cooling via the mounting surface. The coil resistance is rated at 1.8 ohms. Its inductance is measured at 7.5 mH.
The PMB33E-10100-03 servo motor includes three Hall effect sensors for rotor position detection. These sensors are spaced 120° electrically and operate on 5 VDC. The output type is either open collector or push-pull, depending on the model. A built-in PTC thermistor helps monitor internal temperature rise. The thermal resistance is specified at 0.78 °C/W. The thermal response time of the motor is 28 minutes. It is suitable for standard vibration and shock conditions in industrial areas.
Frequently Asked Questions about PMB33E-10100-03:
Q: What challenges arise with IP40 rating of PMB33E-10100-03 servo motor?
A: The PMB33E-10100-03 servo motor lacks moisture sealing, requiring enclosed installations. Exposure to oil mist, water spray, or dust-laden air may reduce reliability.
Q: Why is rotor inertia minimized in the PMB33E-10100-03 servo motor?
A: The PMB33E-10100-03 servo motor’s low inertia enhances acceleration and reversals. However, it may struggle with an inertia mismatch in high-mass load applications.
Q: What implications does 7.5 mH inductance have in the PMB33E-10100-03 servo motor?
A: The PMB33E-10100-03 servo motor’s inductance limits current ripple under PWM control. But it also slows response in ultra-fast servo loops without tuning compensation.
Q: How does 0.78 °C/W thermal resistance affect PMB33E-10100-03 servo motor use?
A: The PMB33E-10100-03 servo motor transfers heat slowly through its frame. This requires careful mounting to avoid thermal saturation during long-duty cycles.
Q: Why are Hall sensors spaced 120° in the PMB33E-10100-03 servo motor?
A: The PMB33E-10100-03 servo motor’s 120° electrical spacing ensures stable commutation. Improper phasing during integration may result in torque ripple or direction reversal.
