- B5-are usually larger and designed for higher stability requirements, often found from size 132 onwards. sind in der Regel größer dimensioniert und für höhere Stabilitätsanforderungen ausgelegt, oft anzutreffen ab Baugröße 132.
- B14-are usually larger and designed for higher stability requirements, often found from size 132 onwards. are more compact and especially suitable for applications with limited installation space.
- In addition to these main types of electric motor flange there are also special variants such as the medium-sized B14gr flange, whose Italian versions are sometimes delivered without threaded holes for the fastening screws.
Distinction of main flange types: B5 and B14
The IEC 60072-1 standard defines the exact flange dimensions.The B5-flange (large) is especially stable (often from size 132, with an outer diameter of typically 300 mm). The B14-flange (small) is comparatively more compact. The choice of the appropriate electric motor flange depends on the specific application and technical requirements..
Special case B14gr and special flanges
Variants such as the B14gr-flange (medium-sized) also exist. Italian versions of the B14gr flange are sometimes delivered without threaded holes (here the assembly is done with nuts). ATEK also offers special flanges (for IEC sizes 63-90) as a non-separately available upgrade to meet specific requirements for the Motor flange .Check: Mastering technical details and selection criteria
Dimensions of the motor flange for compatibility
The outer diameter, pitch circle diameter (PCD), and centering diameter of the electric motor flange are crucial for compatibility (example B5 size 132: typically 300mm outer-ø, 265mm PCD). These dimensions of the connection flange must match exactly with the counter plate of the machine. The shaft dimensions (e.g., 38x80mm) are also relevant in this context.
Handling deviations from the standard
Standard deviations during Motor flange (e.g., in so-called “progressive e-motors” or older models) require a precise measurement comparison (e.g., with AQ Pluss motors). A careful examination of the centering diameter on the electric motor flange is important for correct alignment. ATEK assists with gear boxes and motors..
Materials and their impact
The housing material of the motor (aluminum: lightweight, good heat dissipation; gray cast iron: robust) influences weight, corrosion resistance, and thermal management, which also indirectly affects the properties of the flange connection on the motor. The material choice should be based on operating conditions and expected service life.. Stainless steel gear boxes, often with specialized motor flanges,are suitable for hygiene requirements.Applying: Flange motors in industry and special cases
Areas of use for motors with connection flange. in the industry
flange motors are widely used in machine construction (e.g., for pumps), in the packaging industry (for conveyors), and in machine tools (for spindles). A 4kW B35 flange motor for example, drives hydraulic pumps (with 26.7Nm torque) in agriculture and construction. The flange mounting of the electric motor allows for high versatility in application. ATEK offers servo motor-supported drive train solutions..
Specific requirements for the electric motor flange: Hydraulics and theater
flange motors are excellently suited for direct mounting to hydraulic pumps, whereas the Motor flange a stable connection is ensured. In theatrical technology (e.g. with motors featuring dual brakes), high demands are placed on the reliability and safety of the mounting flange . The design of the electric motor flange must take into account the loads occurring and the necessary safety factors.
special cases regarding Motor flange: spare parts and specific industries
special flanges (e.g. a spare part designated “FLANGE ELECTRIC MOTOR – 175301 Toyota”) are often difficult to identify. For spare parts for an electric motor with a flange, precise measurement and type matching are crucial. ATEK’s modular system provides flexible solutions here, such as modular gear boxes with a servo motor adapter plate, allowing for adaptation to various motor flanges .Optimizing: operation, maintenance, and troubleshooting of flange motors
motor operating modes and the electric motor flange: the S6 operation
the S6 operation (periodic intermittent operation, typical for applications such as sawing or milling) places special demands on the motor and indirectly also on the stability of the flange connection on the motor.. IE3 motors may be unsuitable in this operating mode, as their higher inertia and impedance can lead to thermal overload. Motors of the ABM-D series are often better alternatives here (also for repair or retrofit).
- The S6 operation (periodic intermittent operation) places special demands on the thermal design of electric motors.
- IE3 motors can be thermally overloaded in S6 operation due to their higher inertia and impedance and are therefore not always the best choice.
- Adequate thermal protection, often realized through PTC thermistors (NTCs) starting from size 80, is crucial for the longevity of the motor.
- Standard overload relays often do not provide sufficient protection in S6 operation; a complete motor protection switch is more sensible here.
- Watch out for typical signs of motor problems such as unusual noises, overheating, or strong vibrations.
- Possible causes for such problems include overload, insufficient cooling, mechanical imbalance, or improper alignment of the motor.
- Early detection and resolution of issues is crucial to avoid larger damages and costly downtime.
- In the event of a defect, a cost-effective assessment between repair (especially with older or special motors like the ABM-D series) and purchasing a new one should be made, considering downtime costs and energy efficiency.
Thermal protection
Adequate overheating protection is important for any electric motor, especially in demanding flange motor-applications. Motors (from size 80) often come with PTC thermistors (NTCs) that require external triggering devices. Conventional standard overload relays often do not provide sufficient protection in S6 operation; a complete motor protection switch is more sensible here.
Typical problems and cause detection
Motor issues such as unusual noises, overheating, or strong vibrations require a precise diagnosis (possible causes: overload, insufficient cooling, mechanical imbalance, or improper alignment of the motor at connection flange.). An early detection and resolution of issues at the electric motor and its flange connection prevents larger damages and costly downtime. ATEK assists with electric motors with brakes.
Repair or purchase: economic aspects
A repair (especially for older or special motors, like those of the ABM-D series) may be more economical than purchasing a new one. A careful cost comparison (repair costs vs. new purchase price, including possible downtime costs) is advisable before making a decision regarding the electric motor with its flange. However, more efficient new motors are often the better choice in the long run.Sourcing: sources, costs, and delivery times for flange motors
Sources for electric motors with flange
flange motors are available through various channels: online shops and specialized retailers offer a wide range. The prices for standard versions (e.g. 1500 rpm, with B14 Motor flange) can vary between €87.70 and €265.44. A comparison of offers and checking the availability of the desired electric motor flange is important. ATEK Drive Solutions assists with buying electric motors.
Price factors
The prices for an electric motor with flange vary greatly depending on performance, frame size, degree of protection, efficiency class, and the specific flange type (e.g. B5, B14). Special versions or motors for S6 operation are usually more expensive than standard models. A 7.5kW aluminum motor with a common connection flange. costs approximately €300-400.
Delivery times and shipping options
The delivery time for a electric motor with flange is often only 3-4 days within Germany. Many suppliers offer free shipping above a certain order value (e.g. €1000).
