B14 Flange-Mounted Electric Motors

B14 flange-mounted electric motors are compact electric motors with a small flange connection. These motors have no foot connection; the motor is fixed directly to the machine, gearbox, pump, fan housing or special connection surface via the small flange located on the front cover part. The B14 mounting type is very frequently preferred especially in narrow spaces, compact machine designs and small-to-medium-power industrial applications.

B14 flanged electric motors are widely used in gearbox systems, small pumps, fans, packaging machines, conveyor auxiliary equipment, food machines, textile machines, agricultural machines, mixers, dosing systems, automation equipment and general machine manufacturing applications. Thanks to its small flange structure, the motor can be connected directly to the machine and offers a mounting solution that takes up less space.

What Is a B14 Flange-Mounted Electric Motor?

A B14 flange-mounted motor is a footless electric motor with a small flange connection. While a large flange is used in the B5 mounting type, a smaller-diameter flange connection is found in the B14 mounting type. For this reason, B14 motors are generally preferred in more compact machines and in systems with limited mounting space.

In B14 flange-mounted motors, the connection is made using the threaded holes or connection holes on the front flange of the motor. The motor is connected directly to the machine body or the gearbox input. When the correct centering diameter and the correct shaft dimension are selected, the motor and the equipment operate on the same axis and power transmission takes place more soundly.

What Should Be Considered When Selecting a B14 Flange-Mounted Motor?

When selecting a B14 flange-mounted electric motor, motor power and speed alone are not sufficient. The small flange dimensions, shaft diameter, shaft length, centering diameter, connection hole diameter and key dimension must definitely be checked.

If the wrong B14 flange dimension is selected, the motor may not connect to the machine or the gearbox. If the centering diameter is not suitable, the motor axis may operate off-center. This situation can lead to problems such as vibration, bearing failure, coupling problems, strain at the gearbox input and early wear in the equipment.

The main dimensions to be considered in B14 flange-mounted motors are as follows:

D dimension: The motor shaft diameter.
E dimension: The motor shaft output length.
M dimension: The center diameter of the flange connection holes.
N dimension: The flange centering spigot diameter.
P dimension: The outer diameter of the flange.
S dimension: The flange connection hole diameter or screw size.
Key dimension: The keyway dimension on the shaft, important for the coupling, pulley or gearbox connection.

Common Dimensions in B14 Flange-Mounted Electric Motors

The table below is of a general reference nature for B14 small-flange electric motors. Dimensions may vary according to the manufacturer, motor series, number of poles and special design. Before ordering, verification must definitely be made with the technical drawing or catalog dimension of the motor.

The Difference Between B14 and B5 Mounting

B14 and B5 flange-mounted electric motors are in the flanged motor group. However, the main difference between them is the flange dimension.

B5 motor: A large-flange, footless motor type. It connects to the machine with a larger flange surface.
B14 motor: A small-flange, footless motor type. It offers a more compact connection area.
B34 motor: A footed + small-flange motor type.
B35 motor: A footed + large-flange motor type.

While B14 flange-mounted motors are mostly used in small and medium-power machines, B5 flange-mounted motors are preferred in systems requiring a larger flange connection. For this reason, when making a selection, not only the motor power but also the connection surface and flange dimensions on the machine must be taken into account.

Advantages of B14 Flange-Mounted Motors

B14 flange-mounted electric motors provide the possibility of easy mounting in narrow spaces thanks to their compact structures. Thanks to the small flange connection, the motor can be connected directly to the machine body or the gearbox. This structure is an important advantage especially for manufacturers who want to save space on the machine.

When the correct flange and shaft dimensions are selected, B14 motors provide proper alignment, low vibration and efficient power transmission. In small and medium-power applications, they offer both ease of mounting and practicality of maintenance. The reason they are frequently preferred in gearbox systems, small pumps and auxiliary machine equipment is this compact and practical connection structure.
