Product Description:
The Pacific Scientific's PMB31B-10100-00 brushless servo motor is designed to provide torque and speed control in demanding motion systems. It is built with a NEMA Size 34 frame for precise positional feedback. The motor can be integrated into a wide range of automation setups requiring accurate servo operation.
The steady functioning under constant load is made possible by the PMB31B-10100-00 brushless servo motor, which has a continuous stall torque of 2.1 Nm and a continuous stall current of 2.7 ARMS. Typical mid-range motion patterns are matched by the rated speed of 2,700 rpm. The PMB31B brushless servo motor's constant speed, resolver feedback, and controlled torque make it an ideal candidate for integrated control loops. Peak current is 6.0 A and peak torque is 4.7 Nm for short-term high-load performance. For designs that are concerned about their footprint, the 134.1 mm stack length is ideal. A resolver sensor is built into the servo motor, allowing it to receive analog data for both angle and speed. Current demands from industrial automation systems are met by the motor winding, which supports 2.7 A. Couplings or pulleys can be supported by the shaft, which is round in shape. Flying leads with AMP connectors are part of the connection type; these facilitate wiring in system assemblies.
The PMB31B-10100-00 servo motor is a comprehensive and economical line type that is suitable for a wide range of applications. The no-load speed is up to 4,300 rpm, allowing for increased throughput when load changes are less. The inertia of 0.14 ×10⁻³ kgm² is ideal for control systems that demand consistent acceleration. The inductance is 19.6 mH, which allows for compatibility with matched servo drives. The continuous rated torque is 1.9 Nm, which equals 16.9 lb-in. The motor works with system setups that demand constant torque-to-inertia ratios.
Frequently Asked Questions about PMB31B-10100-00:
Q: Why does the PMB31B-10100-00 include a resolver sensor instead of an encoder for feedback?
A: The resolver sensor provides durable analog feedback that enables reliable position tracking in varying operating conditions and improves long-term signal stability.
Q: Does the PMB31B-10100-00 support applications requiring high-speed motion and quick acceleration response?
A: Yes, with a no-load speed of 4,300 rpm and low inertia, the motor handles quick speed changes efficiently.
Q: Why does the PMB31B-10100-00 use a round shaft instead of a keyed or flat shaft?
A: The round shaft allows easier integration with custom couplings or gear assemblies in motion systems.
Q: How does the 2.7 ARMS winding of the PMB31B-10100-00 affect its continuous performance output?
A: The 2.7 ARMS winding supports stable current flow, enabling consistent torque delivery during continuous operation.
Q: Do the flying leads with amp connectors on the PMB31B-10100-00 simplify the connection process?
A: Yes, the flying leads with amp connectors reduce installation time and allow quick connection to control systems.
