What are the mounting methods for three-phase induction motors, and how do different mounting methods suit specific equipment?

The mounting method of a Three Phase Asynchronous Motor  directly affects the equipment’s layout, operational stability, and ease of maintenance. Our company offers a variety of internationally standard mounting methods to meet the installation requirements of different mechanical equipment. The primary mounting methods and their applicable scenarios are as follows:

1. B3 Horizontal Mounting (Foot Mounting): The motor base features foot bolt holes. It is placed horizontally on the equipment base and secured with foot bolts. This is the most commonly used mounting method, suitable for most horizontally operating mechanical equipment such as conveyor belts, fans, water pumps, machine tools, and compressors. It offers simple installation, high stability, and convenient maintenance, with ample stock available.

2. B5 Vertical Mounting (Flange Mounting): The motor end cover features a circular flange. The motor is mounted vertically on the top or side of the equipment and secured with flange bolts. This is suitable for vertically operating equipment such as vertical mixers, vertical pumps, gear reducers, and lifting equipment. It saves space, ensures high concentricity, and operates vibration-free.

3. B35 Dual-Purpose (Horizontal/Vertical) Mounting: Combines both foot and flange mounting structures, allowing for both horizontal and vertical installation. It offers exceptional versatility and is suitable for equipment with limited installation space or requiring flexible mounting options, making it the preferred multifunctional mounting method for international customers.

4. B14 Small Flange Mounting: Features a small flange plate, suitable for low-power motors and small mechanical equipment. It provides a compact installation with minimal space requirements.

The dimensions of all mounting configurations strictly adhere to IEC international standards. Flange dimensions, foot mounting hole spacing, and shaft extension lengths are compatible with internationally standard equipment, allowing customers to install the motor directly without modifying their equipment’s mounting structure. Additionally, we can customize non-standard mounting dimensions, extended shafts, shortened shafts, and dual shaft extensions to meet specific installation requirements, ensuring the motor fits perfectly with the customer’s equipment and operates smoothly after installation—free from vibration and noise.
