MOTOR MANUFACTURER · Anhui, CHINA
ANHUI WANNAN ELECTRIC MACHINE CO.,LTD.
Wannan's catalogue spans several different motor architectures. Start with the load, supply and operating environment; a shared manufacturer name does not make these series interchangeable.

01 / CHOOSE A ROUTE
These are starting paths drawn from the manufacturer's published range, not a substitute for a model-specific datasheet and drawing.
YE5 is a three-phase induction range offered for conventional industrial loads such as pumps, fans, compressors and material-handling machinery. Check the applicable efficiency standard, pole count, frame, duty and supply for the quoted market.
Confirm before ordering Request a model-level efficiency table and mounting drawing; do not infer one rating from the whole series.
View YE5 three-phase induction motor →TYCP is a converter-driven permanent-magnet synchronous range. The motor and inverter must be selected together for the required torque-speed profile and cooling arrangement, especially at low speed.
Confirm before ordering Specify the drive, feedback or control mode, operating speed band and cooling at the exact rating.
View TYCP permanent-magnet synchronous motor →YFB5 is presented as a dust-explosion-protected three-phase range, a different decision from buying a standard enclosed motor. The hazardous-area classification and ambient conditions must match the precise offered configuration.
Confirm before ordering Ask for the current certificate and marking tied to the quoted model and intended installation zone.
View YFB5 dust explosion-proof three-phase motor →Z4 is a separately excited DC series for machinery that requires a defined DC drive and field arrangement. A motor-only comparison hides the rectifier, ventilation and control requirements.
Confirm before ordering Confirm armature and field supply, speed range, cooling and the approved drive package.
View Z4 separately excited DC motor series →02 / CAPABILITY & EVIDENCE
The company publishes workshop, assembly-line, laboratory and final-test material. That supports a conversation about manufacturing and test records; it does not certify every offered model or current production slot.
The Chinese and English company sites identify Anhui Wannan Electric Machine Co., Ltd. in Jing County, Anhui. An independent SPS exhibitor listing names the same company and Nanhua Road location.
Company-published factory material depicts motor production, an assembly line, a test-control center and final testing. For a purchase, ask which tests and release records apply to the exact series and manufacturing site.
The company's catalogues discuss efficiency and hazardous-area requirements, but a family label is not proof that every configuration has the same approval. Verify the legal holder, certificate scope, validity and motor nameplate before relying on any claim.
03 / AVOID A WRONG MATCH
Not from the headline efficiency claim alone. Compare frame and shaft dimensions, starting and control architecture, converter compatibility, torque at working speed and the cooling method of the proposed model.
No. Provide the site's dust classification, temperature and ingress conditions, then request the exact offered motor's marking, certificate and installation instructions.
No. The official Z4 pages describe multiple frames, voltage and speed options. Ask for the offered model code, its armature and field ratings, ventilation arrangement and matching drive data.
04 / PREPARE AN INQUIRY
Choose one route above and attach the current machine drawing or duty schedule when available. The questions differ between an induction replacement, a PM drive, a dust-area installation and a DC system.
Load type, required output, continuous and peak demand, speed range, starts per hour, ambient conditions and expected operating cycle.
Supply voltage and frequency, inverter or rectifier model, control method, brake or feedback need, and hazardous-area classification if applicable.
Frame, mounting, shaft and envelope drawings; quantity, destination, required nameplate/efficiency or safety documents, test records and delivery target.
