Xindali Motor

Wuxi Xindali Electric Machine Co.,Ltd.

Wuxi Xindali focuses on crane and metallurgical motors but also lists general-purpose efficient induction machines. Its YZR wound-rotor family is built around a crane's intermittent starts, load changes and rotor-control scheme; a YE4 squirrel-cage motor belongs to a different fixed-speed pump, fan or compressor brief. The official YE4 page contains a title/body mismatch—one introductory sentence calls the motor YE5 even though the detailed introduction calls it YE4. Use the exact manufacturer's model sheet and nameplate to resolve the offered efficiency series before comparing prices.

XINDALI · HOIST DUTY OR GENERAL DRIVE

Xindali motors: crane YZR duty versus general YE4 efficiency

Explore the published range ↓

01 / START WITH THE MACHINE

Crane service and continuous plant duty require different motor evidence

YZR: wound-rotor crane and metallurgy service

Xindali's YZR page explicitly distinguishes its wound rotor from the squirrel-cage YZ family and gives frame 112–560 with a 1.5–710 kW family range. Its stated use is lifting and metallurgical equipment with high overload/mechanical-strength demands. Those broad boundaries do not determine a hoist's permissible starts per hour, duty class, rotor-resistance stages, brake size or gearbox matching. The rotor circuit and controls are part of the purchase, not an afterthought.

Confirm before ordering Send hoist or travel function, lifted mass, reeving/gear ratio, cycle chart, start/reverse frequency, thermal duty, control method, rotor resistor and brake specification. Ask for the exact YZR frame/poles/rating, allowable starts and overload curve, rotor connections and mating drawing.

YE4: fixed-speed general machinery

The separate YE4 page identifies an enclosed squirrel-cage, IP55 general-purpose motor for fans, pumps, compressors and similar loads, with a page-level 132–400 frame and 5.5–560 kW range. It references GB18613-2020 grade 2 efficiency in its detailed YE4 paragraph. However, its introductory paragraph incorrectly calls the range YE5 and uses grade-1 language. Do not treat that mixed text as a current certificate or select a model from the headline alone.

Confirm before ordering Provide load torque, required speed, supply, start method, environmental and mounting conditions. Require the quoted model's full YE4 designation, nameplate, efficiency test/certificate scope and outline; explicitly resolve the manufacturer's YE4/YE5 text inconsistency in writing.

02 / YZR SYSTEM FIT

A wound-rotor motor must be quoted with its control and brake assumptions

Separate motor, rotor circuit and brake

The YZR listing concerns a motor family, not a complete lifting package. A legacy crane may use external rotor resistance and a separate mechanical brake; a modernization may need a different motor/control architecture. Ask the supplier to state what is included, the rotor termination and resistor control, brake interface and safe stop sequence.

Match the actual intermittent duty

Average shaft kW misses repeated starts, counter-torque braking, reversals and overload. Provide a time-resolved movement cycle and duty designation, then request permitted starts and thermal-rise evidence at the intended ambient. Do not assume the YZR family 710 kW upper end or marketing claims apply to the required frame.

Keep hazardous-area claims separate

Xindali's site also lists separate explosion-protected crane series. The YZR page's generic application tiles mention oil and mining but do not establish explosion protection for the ordinary YZR code. If a zone classification applies, seek a separately approved exact model and matching installation documents.

03 / FAIR COMPARISON

Give each supplier the same measured requirement

What existing equipment must be matched?

Supply current nameplate, shaft/mount/coupling drawing, terminal and rotor-circuit photos, gearbox and brake data. For YE4 replacements, add pulley or pump curves and starting limits; for YZR, add hoist load path and control stages.

Which operating evidence will be accepted?

For YZR, agree loaded start, brake release/hold, reverse and repetitive-cycle temperature tests. For YE4, compare measured full-load current, efficiency at the selected rating, vibration/noise and thermal rise. Request reports tied to the exact model, not an unrelated family badge.

Which standard and revision governs?

Ask for an exact code, current standard, efficiency scope and production revision. The manufacturer's YE4 page mixes YE4 and YE5 wording; explicitly request the matching nameplate and documentation before purchase. Government historical product listings can corroborate past entries but do not replace a current model document.

04 / VERIFIED VS OPEN

The operating company and families are documented; the exact build remains open

Corporate identity

Xindali's site identifies 无锡新大力电机有限公司 in Wuxi's Huishan industrial area and lists crane/metallurgical, VFD, brake and general-purpose motor categories. A public Chinese government product list names the same company for a historical YE4 (IP55) series entry; that checks identity and a bounded product family, not a current blanket approval.

The published conflict

The maker's YZR page distinguishes wound from squirrel-cage rotors. Its YE4 detail paragraph describes a grade-2 YE4 motor, while the opening promotional sentence says YE5/grade 1. The public profile retains that discrepancy and asks for exact model evidence instead of silently choosing the more attractive claim.
