Product Description:
The PMB33F-00200-01 Brushless Servomotor is designed and manufactured by Pacific Scientific. The company is known for manufacturing reliable and industrial-grade motion control products. Its feedback sensor is a resolver, which allows for accurate location sensing. This servomotor model delivers strong performance with optimized torque and speed ratings.
The PMB33F-00200-01 Brushless Servomotor has a flat shaft design for stable mechanical coupling and improved alignment. For safe and adaptable connections, the motor comes with flying leads with MS connectors. This motor is a NEMA Size 34 frame with 3 3-stack lengths. The integrated resolver and electrical characteristics support efficient closed-loop operation. The nominal current of the winding is 11.0 A which enables high torque delivery. The PMB Brushless Servomotors operate with a continuous stall current of 9.0 A. The rated current for achieving peak torque is 21.2 A. It delivers a peak stall torque of 12.5 Nm and a maximum rated torque of 12.5 Nm. While the ongoing rated torque is 4.1 Nm, the continuous stalling torque is 5.4 Nm. The motor supports an operating speed of 4500 rpm under load. The no-load speed reaches up to 5700 rpm. Its inductance is specified at 2.8 mH, contributing to smooth operation. The rotor inertia is measured at 0.40 x 10^-3 kgm^2 which supports fast acceleration.
The PMB33F-00200-01 Brushless Servomotor is built with an IP40 protection class rating. This allows installation in clean environments without exposure to dust or liquids. The compact and robust design makes it suitable for tight motion control systems. The PMB Brushless Servomotors are well-suited for applications requiring accurate speed and torque control. This motor offers consistent performance with long service life and low maintenance.
Frequently Asked Questions about PMB33F-00200-01:
Q: How does the flat shaft design of the PMB33F-00200-01 improve system stability?
A: The flat shaft design ensures better mechanical coupling and minimizes rotational slippage. This helps maintain precise alignment under high-load torque conditions.
Q: Why is rotor inertia important in the PMB33F-00200-01 Brushless Servomotor?
A: The low rotor inertia of 0.40 x 10^-3 kgm² enables faster acceleration. This is crucial for dynamic positioning and rapid cycle operations.
Q: How does the resolver feedback enhance accuracy in the PMB33F-00200-01?
A: The resolver continuously tracks rotor position with high precision. This allows for smooth closed-loop motion control even in variable load applications.
Q: What advantage does the 2.8 mH inductance provide in motor performance?
A: The 2.8 mH inductance reduces current ripple in the windings. This helps achieve smoother motion and lower torque ripple during operation.
Q: How do MS connectors benefit the PMB33F-00200-01 in industrial setups?
A: The MS connectors offer a secure locking mechanism for flying leads. This ensures vibration-resistant connections in high-motion environments.
