Product Description:
The PMB33F-10101-00 belongs to the PMB series of brushless servo motors. This motor is developed by Pacific Scientific. The motor features a NEMA 34 standard frame size. It is built with a three-layer stack for enhanced torque capability. A flat shaft end is used for reliable mechanical interfacing.
The PMB33F-10101-00 servo motor integrates a resolver for accurate position feedback. Flying leads with AMP plugs are provided for electrical connections. It holds an IP40 environmental rating for basic internal protection. The winding code F supports a nominal stall current of 11.0 A at 240V AC. It maintains a continuous stall torque rating of 5.4 Nm. The motor achieves a maximum torque of 12.5 Nm at the locked rotor condition. The rotor angular mass is about 2.8 kg·cm² for providing smooth motion control. The PMB33F-10101-00 servo motor offers a no-load speed of 5700 rpm. It provides a rated continuous torque of 4.1 Nm under normal operation. The rated speed is set at 4500 rpm for balanced operation. The servo motor has a continuous stall current drawn of 9.0 A. It can handle a peak current of 21.2 A during demanding tasks. The line-to-line inductance is measured at 0.40 mH. The Neodymium Iron-Boron magnets are used in the motor to achieve high torque density.
The insulation class of the PMB33F-10101-00 servo motor is F. This shows that the motor supports thermal operation up to 155°C. Double-shielded bearings are used to protect against debris and contaminants. The core of the motor includes exposed laminations for effective heat dissipation. An optional thermistor is available for over-temperature detection and system safety. The compact design and flying lead connections support easy installation. The rotor inertia and stack design contribute to stable acceleration in industrial automation.
Frequently Asked Questions about PMB33F-10101-00:
Q: What influences rotor dynamics in the PMB33F-10101-00 servo motor?
A: The PMB33F-10101-00 servo motor uses a 2.8 kg·cm² rotor and triple-layer stack for optimized acceleration. This setup enhances response and reduces overshoot during rapid cycles.
Q: How does resolver integration affect the PMB33F-10101-00 servo motor control resolution?
A: The PMB33F-10101-00 servo motor includes analog resolver feedback that interpolates to ~12-bit resolution. It enables smooth and accurate velocity control with compatible drives.
Q: What limits thermal dissipation in the PMB33F-10101-00 servo motor?
A: The PMB33F-10101-00 servo motor’s thermal dissipation is limited by its IP40 rating and passive cooling. Lack of forced-air or liquid cooling reduces overall heat handling.
Q: How is torque linearity maintained in the PMB33F-10101-00 servo motor design?
A: The PMB33F-10101-00 servo motor maintains torque linearity via precision windings and strong Neodymium magnets. These reduce detent torque and improve motion smoothness.
Q: What cable requirements apply to the PMB33F-10101-00 servo motor?
A: The PMB33F-10101-00 servo motor requires shielded power cables with twisted resolver lines. This minimizes EMI, especially in systems with long runs or high switching speeds.
