AFPM generator sourcing for compact low-speed power systems that need custom voltage, low cogging, and durable outdoor packaging.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Start-up torque | Application-specific | Low-speed renewable systems require smooth startup before rated power can matter. |
| Output voltage window | Winding and RPM dependent | Voltage must match battery, rectifier, inverter, or load behavior across real speeds. |
| Corrosion protection | Indoor, outdoor, marine, or sealed module | Magnet coating, bearing selection, fasteners, and housing finish drive service life in wet environments. |
| Thermal rise under load | Load profile and ambient dependent | Generator heat rise depends on real electrical load, rectifier behavior, and available cooling surface. |
Application pages should help buyers decide what to validate first. This flow connects the scenario, architecture fit, sample evidence, and supplier handoff records before a pilot lot is approved.
| Step | Decision Logic | Evidence to Request |
|---|---|---|
| Duty mapping | Rated power, RPM range, voltage target, and load interface; Outdoor or marine environment, IP target, and corrosion exposure | Operating profile, load points, envelope drawing, and controller assumptions. |
| Architecture fit | RPM distribution, rectifier/load behavior, and thermal rise; Magnet coating, corrosion control, sealing, and maintainability | Cooling route, mounting interface, feedback method, and risk items that change the AFPM topology. |
| Prototype gate | Start-up torque, Output voltage window, Corrosion protection, Thermal rise under load | Measured sample records matched to the application duty, not just no-load bench data. |
| Pilot release | Design against actual RPM distribution and load profile rather than brochure rated speed.; Confirm coating, sealing, drain path, and environmental inspection plan.; Review voltage window, load curve, protection strategy, and thermal rise with the actual power electronics path. | Approved CTQs, revision control, nonconformance handling, packaging, and delivery milestones. |
Yes, if drawings, measurements, output target, and operating environment are available for review.
Cogging reduction depends on pole-slot selection, magnet shape, skew or segmentation strategy, airgap, and control of rotor/stator tolerances.
Useful records include winding resistance, hipot, no-load voltage at defined RPM, runout, balance, sealing inspection, coating confirmation, and heat-rise notes under representative load.
