Hengda Motor

Wuxi Hengda Motors Co.,Ltd.

Wuxi Hengda serves industrial equipment from its Wuxi base, including general high-efficiency motors and motion-control drives. The two represented ranges answer different requests. YE4 is a self-fan-cooled, three-phase induction route for a defined constant-speed load. YPNC is described by Hengda as an asynchronous servo route for machine spindles and other controlled axes, with cooling and feedback options that must be resolved with the drive. Before comparing quoted kilowatts, identify whether the equipment needs fixed-speed efficiency or a controlled speed/torque envelope.

01 / TWO DIFFERENT JOBS

A pump duty and a spindle axis do not share a selection sheet

YE4: general-purpose fixed-speed drive

Hengda describes YE4 as a three-phase, enclosed self-fan-cooled squirrel-cage induction series. Its official family page lists H80–450, 0.55–1,000 kW, 380 V/50 Hz as the standard reference, two/four/six/eight poles, IP55, IC411 and S1; special voltages and frequencies are described as custom options. The page has model rows with different currents, speeds and connections. The family maximum must not be treated as available in every frame or pole count.

Confirm before ordering For a fan, pump or compressor, send the load torque curve, operating hours, starting method, supply, site altitude/ambient, coupling and mounting. Request the exact YE4 row, efficiency evidence for that model, starting-current/torque data and drawing. If a VFD is planned, ask for written motor-drive/cooling suitability rather than assuming an IC411 fixed-speed listing covers slow operation.

YPNC: a controlled machine drive

The maker calls YPNC an asynchronous servo motor for a main-machine drive, citing machine-tool spindles, packaging machinery, injection machines and wire-drawing equipment. Its catalogue gives H80–200 and 0.55–55 kW, with 380 V/50 Hz reference, two/four/six poles, IP55 and S1. It lists IC411 or IC416 and B5/B35 choices; its separate manual also shows configurable encoder/resolver, cooling, shaft, brake and thermal-protection codes. That is a configuration system, not proof every option coexists on one motor.

Confirm before ordering Give spindle torque-speed and inertia curves, acceleration/reversal cycle, drive DC/AC supply, encoder or resolver interface, low-speed load, cooling air, shaft and flange drawing, brake need and stopping strategy. Ask for the exact YPNC code and matched drive/feedback, continuous and timed-overload curves, and acceptance test at the required duty.

02 / PREVENT FALSE EQUIVALENCE

Efficiency class, cooling and servo behavior have different evidence

An IE4 label applies to the selected YE4 rating

Hengda's YE4 page states an IE4 series efficiency target and provides model-specific performance rows. Ask for the offered code's test/certification scope, rated efficiency at the required voltage and frequency, and the duty calculation. A broad label does not give the efficiency of an unlisted custom frequency or inverter arrangement.

YPNC is described as asynchronous servo

The YPNC manual explicitly calls the range an asynchronous servo motor. Do not compare it as a permanent-magnet servo merely because both may be used for motion control. Establish the drive algorithm, feedback device and torque-speed/field-weakening limits for the actual package.

Cooling must work at the slowest loaded speed

YE4's standard IC411 uses a shaft fan; YPNC lists IC411 or IC416 alternatives. With prolonged low-speed spindle torque or a VFD on a standard motor, shaft-fan cooling can be inadequate. Request the chosen cooling code and thermal-rise evidence at the minimum operating speed, not just at rated speed.

03 / SPECIFY THE MACHINE

Send the operating points and interfaces before requesting price

What does the machine actually do?

For a constant-speed installation, record normal and peak load, starting method, operating hours and electrical tariff assumptions. For a spindle, include speed range, acceleration, reversals, tool/load inertia, low-speed torque and emergency-stop behavior. These data determine whether YE4 or YPNC is the relevant route.

What must be delivered together?

State motor-only versus a motor, VFD/servo drive, feedback and cooling fan package. Specify who commissions the controller and supplies wiring, parameter files and spare parts. For YPNC, get the code-level encoder/resolver, mounting and brake options in the bill of materials.

How is a substitute accepted?

Require dimensioned shaft/flange/foot drawings, terminal position, electrical protection and a loaded test at the actual machine points. For YE4, check efficiency, current and thermal rise; for YPNC, check speed regulation, low-speed temperature and stopping/reversal response with the matched drive.

04 / SOURCE AND LIMITS

The company's published ranges are detailed; the order needs a model code

Identity and manufacturing context

Hengda's corporate site identifies 无锡市亨达电机有限公司 in Wuxi and shows general, permanent-magnet and textile motor lines. It publishes dedicated YE4 and YPNC product pages and downloadable motor documents. Website qualification badges are self-published; they do not prove a certificate covers the exact proposed motor.

Catalogue limits that matter

YE4 lists individual rating rows under a broad family envelope. YPNC lists configurable feedback, cooling, brake, shaft and thermal options. Neither a family maximum nor an example code is a complete offer. Request an exact model row, current drawing, operating curve and relevant test/certificate scope for the destination and duty.
