Product Description:

The component number PMB31B-10216-01 is produced by the market giant Pacific Scientific. This brushless servo motor utilizes nominal stall current at 240 VAC maximum is 2.7 A and further adjust the RMS phase current baseline and guides selection of continuous current limits and protection settings. The sensor includes a digital encoder with commutation for supplying both commutation timing and position feedback. It enables drives to execute accurate electronic commutation with a typical rated speed at 36 V AC with 1,000 rpm as well.

The NEMA Size 34 prescribes the flange and bolt pattern for mechanical mounting and simplifies integration into NEMA-compatible frames. Its encoder resolution is 4096 ppr to yield a high pulse density per revolution and deliver finer closed-loop position increments for accurate indexing. The inclusion of flying leads with MS connectors provides rugged, keyed connections and supports repeatable harness mating during assembly and maintenance. Number of poles is 8 which determines the electrical pole count and converts shaft rpm into electrical frequency for drive tuning. Winding resistance line-to-line measures 6.0 Ohms which defines electrical impedance and helps calculate voltage drop and thermal dissipation in continuous operation. Stack length multiple equals “1” which denotes the standard stator axial length and simplifies envelope planning.

Enclosure rating of PMB31B-10216-01 industrial motor is IP40. This restricts particulate ingress larger than one millimeter and demands cabinet or enclosure mounting in dusty environments. Its maximum speed reaches 10000 rpm which marks the mechanical ceiling for safe rotation and determines bearing selection and coupling limits. Following the flange mount fixes axial mounting method and standardizes bolt pattern and clamp loads. Its typical rated torque at 36 V AC equals 0.22 Nm, specifying a nominal torque available for continuous operation and determines process force capability.

Frequently Asked Questions about PMB31B-10216-01:

Q: What role does the typical rated speed (36 V AC) play for PMB31B-10216-01 in application matching?

A: The typical rated speed at 1,000 RPM defines the nominal operational speed for rated torque and which therefore processes synchronization to match motor mechanical output to application demands.

Q: How does motor size influence mechanical integration for PMB31B-10216-01?

A: Motor size of NEMA Size 34 for PMB31B-10216-01 prescribes a standardized flange and bolt pattern which streamlines mechanical mounting.

Q: What control advantage does the encoder resolution provide for PMB31B-10216-01?

A: The encoder resolution of 4096 ppr for this variant increases pulse count per revolution which enhances position granularity and reduces steady-state error in closed-loop position.

Q: How does the connector type impact wiring and maintenance for PMB31B-10216-01?

A: PMB31B-10216-01 features flying leads with MS connectors and supply keyed, rugged connections which enable consistent pin assignment and simplified field replacement.

Q: Why does the pole count matter for PMB31B-10216-01 and how does it influence drive parameters?

A: An 8-pole design by this module sets electrical pole-pair count which converts shaft rpm to electrical frequency.


Internal Product Review

  • ‘‘Drive PMB31B-10216-01 includes a digital encoder with commutation and a flange mount to deliver consistent commutation and straightforward mechanical coupling. Also, the 2.7 ARMS stall current supports predictable drive sizing and reliable short-term torque performance in intermittent duty cycles over anticipated acceleration events. Maintenance intervals remain defined by bearing choice specifically.’’
