ABB M3JP Series (Shanghai) High-Efficiency Flameproof Three-Phase Induction Motors for Hazardous Areas

の ABB M3JP series are low-voltage cast-iron high-performance flameproof three-phase induction motors for hazardous areas manufactured by ABB Shanghai Electric Motors Co., 株式会社. Developed on ABB’s global unified design platform with advanced modular ADEPT design, they represent ABB’s flagship flameproof low-voltage motor range.

Designed specifically for explosive gas atmospheres in Zone 1 and Zone 2, these motors feature ultra-high efficiency (IE3 as standard, IE4 available for selected models) and exceptional reliability, widely used in petrochemical, coal, 製薬, metallurgical and other industries.

2. モデルの命名規則

Complete model example: M3JP160MA4-CT4

説明: M3JP series, 160mm frame, B5 flange mounting, 4 極 (1450回転数), gas group IIC, temperature class T4 flameproof motor.

3. Key Technical Specifications

4. Flameproof Characteristics & 認証

4.1 Flameproof Principle

Featuring Ex db flameproof construction, safety is ensured by two protective measures:

Flameproof enclosure (Ex d): Withstands internal explosion pressure and prevents flame propagation to the external hazardous atmosphere.

Surface temperature limitation (Ex b): Maximum surface temperature of all motor parts does not exceed the limit defined by temperature class (T4=135°C, T5=100°C, T6=85°C).

4.2 Applicable Hazardous Environments

4.3 認証

国内: CQST (China Quality Supervision and Testing Center for Explosion-Proof Products)

国際的: IECEx, ATEX, UL, CSA, 等.

Classification Society: ABS, DNV, LR, 等. (オプション)

6. Cross-Reference Order Codes with Major Global Brands

Below are equivalent order codes for ABB M3JP series flameproof motors against other leading brands, matched by power, 極, flameproof rating and mounting:

7. Selection Guidelines & 交換の推奨事項
8. Flameproof rating matching: Select according to gas group (IIB/IIC) and temperature class (T4/T5/T6) of the hazardous area. IIC motors can replace IIB, but not vice versa.
9. Efficiency selection: IE3 standard for general applications; IE4 premium efficiency for high energy-saving requirements.
10. Cooling method: IC416 with separate fan recommended for VFD applications to avoid overheating at low speeds.
11. Mounting dimensions: Strictly comply with IEC standard dimensions to ensure compatibility.
12. Certification requirements: Confirm required certifications for critical applications (CQST for domestic projects, IECEx/ATEX for international projects).
13. Replacement notes:

Ensure replacement power ≥ original and flameproof rating ≥ original.

Verify mechanical dimensions: shaft height, shaft diameter, keyway size.

Confirm terminal box position and cable entry size match the original motor.

For special environments (marine, 屋外, humid tropical), select correspondingly configured models.
