Product Description:
The PMB31B-00114-02 Brushless Motor has a robust NEMA 34 frame with high performance electrical characteristics and it is capable of delivering substantial torque output under load. The module consumes up to 6 amperes at peak force and its larger frame size ensures mechanical stability, essential for precision automation systems that require strength, consistency and durability.
The PMB31B-00114-02 motor includes a drive rod with a flattened edge which makes it easier to mount gears, pulleys or couplings securely without slippage and its upper limit of torque output is 4.57 nm which is suitable for short bursts when requiring high mechanical effort. It is included with a precise electronic feedback device which is capable of detecting both position and rotation speed and its sensor also helps with electronically timing its internal phases. It is attached with open ended wires that are pre equipped with AMP style electrical connectors which provides flexibility in wiring and makes it easy to link to control electronics or other systems. It can rotate at up to 4300 revs in a minute which represents its top end velocity under minimal friction and no external load and its rotary position sensor is capable of distinguishing 2048 distinct steps per full revolution that enables fine tuned control over positioning and movement.
This PMB31B-00114-02 motor is constructed to withstand tough operating conditions as it is built with durability in mind and despite its robust design it is cost effective. Its drive electronics responsible for managing and powering it is PC3403 which control motion profiles, current control and communication with higher level systems. Its internal coil structure is designed to draw 2.7 amperes of electrical current during normal functioning which reflects its steady-state power consumption under standard operational loads.
Frequently Asked Questions about PMB31B-00114-02:
Q: How does the flat shaft in PMB31B-00114-02 improve mechanical coupling?
A: The flat shaft design prevents slippage when connecting gears or pulleys. This ensures better torque transfer and reliable rotation during high-demand operations.
Q: Why is a digital encoder with commutation used in PMB31B-00114-02?
A: It allows precise rotor positioning and also helps time the motor’s magnetic field cycles. This results in smoother motion and accurate synchronization.
Q: What advantages does a NEMA 34 frame bring to PMB31B-00114-02 installations?
A: It provides a standardized, rugged mounting profile ideal for industrial systems. Its larger footprint helps in heat dissipation and mechanical balance.
Q: How does the 2048 PPR resolution enhance PMB31B-00114-02’s positioning accuracy?
A: It increases feedback detail, allowing for very small movement detection. This enables fine control in automation tasks like pick-and-place or precision cutting.
Q: What role do flying leads with AMP connectors play in PMB31B-00114-02 setup?
A: They provide flexible wiring options and quick, secure electrical connections. This simplifies installation and maintenance in tight or dynamic environments.
