Langrui YEJ-100L2 3 kW Three-Phase Electromagneti | RFQ Sourcing Details

Product overview The YEJ-100L2 is a 3 kW three-phase AC motor equipped with an electromagnetic brake for industrial drive duties. The listed model family includes 2-, 4-, 6-, and 8-pole configurations, with 10 poles also appearing among the available basic specifications.

It is described as a constant-speed motor with direct-on-line starting and S1 continuous duty. Supported configuration details The motor uses a 100 mm frame and is offered with cast-iron or aluminum housing options. Listed supply configurations include 380, 400, 415, 440, and 600 V at 50 or 60 Hz.

Available mounting arrangements are B3, B5, B35, B14, B34, and V1. Enclosure protection options include IP23, IP44, IP54, and IP55, while insulation options include classes B, F, and H. Cooling selections are listed as IC01, IC06, IC411, and IC416. Bearing options include SKF, NSK, C&U, and ZWZ.

The broader YEJ2/YEJ3 description identifies F-class insulation with temperature rise assessed according to class B and gives IP55 and IC411 as series-level configurations.

Because the source also lists alternative insulation, protection, and cooling choices, buyers should confirm the exact construction attached to the ordered model rather than assume that every listed option is included in one motor.

Operating conditions Published operating conditions include an ambient temperature range of -15 to 40°C, altitude up to 1,000 m above sea level, and relative humidity up to 90%. Permitted supply variation is listed as ±5% for voltage and ±2% for frequency. The stated working duty is S1 continuous operation.

Industrial use The series is presented for general industrial environments and machinery without special operating requirements. Listed equipment examples include pumps, fans, compressors, machine tools, reducers, conveyors, packaging machinery, mining machinery, construction machinery, and marine equipment.

Suitability for any specific machine must still be checked against its load, braking cycle, starting method, environment, and mounting interface.

Procurement questions to confirm Before ordering, confirm the required pole count and resulting rated speed, because several pole configurations are associated with the model family.

Specify the operating voltage, frequency, mounting arrangement, housing material, enclosure rating, insulation class, cooling method, bearing selection, and required standard.

Request the exact rated current, efficiency, power factor, starting current, starting torque, maximum torque, brake torque, brake supply details, stopping time, shaft dimensions, and outline drawing for the selected configuration.

Buyers should also verify whether direct-on-line starting is appropriate for the installation and confirm the applicable certification documents for the exact motor supplied.

The listed guarantee period is 12 months, but its start date, coverage, exclusions, and claim procedure should be established in the purchase documentation.
