Product Description:
The Pacific Scientific's PMB33C-00100-03 is a brushless servomotor from their PMB brushless servo motor series. A resolver sensor is built inside the servomotor, allowing for precise feedback in controlled motion applications. The included frame size is in accordance with NEMA Size 34. In applications requiring accuracy and consistency, the servo motor is an efficient option for industrial automation systems.
The continuous stall torque for the PMB33C-00100-03 brushless servo motor is 5.0 Nm, and the continuous rated torque is 4.8 Nm. An additional peak stall torque of 9.7 Nm backs up the highest rated torque of 9.7 Nm. The motor's windings are designated as having a maximum current of 240 V AC and a stack length of 3. Models that are compatible with the servo drives are PC8x2 or SC9x2/SCE9x2. The stall current is 3.8 A nominally and increases to 5.3 A RMS at maximum torque. The precise torque delivery and reliable current regulation are made possible by the 27.2 mH line-to-line inductance. The motor rotor exhibits appropriate acceleration characteristics with an inertia of 0.40 × 10⁻³ kg·m². A flat shaft is a part of the PMB brushless series that makes mechanical integration easier. A PTC thermistor and a shaft seal are added for further protection and monitoring according to the factory-assigned modification code.
A resolver sensor is built inside the PMB33C-00100-03 brushless servo motor to guarantee accurate position detection and feedback. Because the system makes use of flying leads with AMP connectors, wiring is simplified and setup is made easier. The design achieves a balance between compact dimensions and torque output with a stack length of 3. Applications requiring automation and precision benefit from the product's reliable performance. Controlled torque delivery and dependable operation are two criteria that the servomotor satisfies.
Frequently Asked Questions about PMB33C-00100-03:
Q: How does the PMB33C-00100-03 servomotor benefit from a 27.2 mH line-to-line inductance?
A: The 27.2 mH inductance stabilizes current flow that improves torque control. It reduces the current ripple in the winding that ensures smoother operation and consistent torque delivery across varying loads.
Q: Why is the PMB33C-00100-03 designed with a continuous stall torque of 5.0 Nm?
A: The 5.0 Nm stall torque enables sustained torque without overheating. It supports demanding loads at low speeds that maintain operational reliability and prevent torque drops in critical applications.
Q: How does the PMB33C-00100-03 achieve peak stall torque of 9.7 Nm efficiently?
A: The servomotor achieves 9.7 Nm peak stall torque by drawing 5.3 A RMS. This provides short-duration overload capacity that ensures acceleration and quick response in motion sequences.
Q: Why does the PMB33C-00100-03 use a 0.40 × 10⁻³ kg·m² rotor inertia?
A: The rotor inertia of 0.40 × 10⁻³ kg·m² balances acceleration with stability. It reduces overshoot during positioning that ensuring precise control in high-speed and repetitive motion cycles.
Q: Does the PMB33C-00100-03 benefit from the customization code with the shaft seal and PTC thermistor?
A: The customization ensures protection and monitoring. The shaft seal limits contamination entry. The PTC thermistor monitors temperature rise that enhances motor safety and operational consistency during extended cycles.
