What is C flange motor?
C flange motors always have threaded mounting holes in the face of the motor. of D flange, the flange diameter is normally larger than the body of the motor and it has clearance holes suitable for mounting bolts to pass through from the back of the motor into threaded holes in the mating part.
What is a flange mounted motor?
Flange Mounting Motors are designed for wide application in various types of industries. The Flange Mounting Electric Motors are with sintered iron bush bearings lubricated for life. End-shields are either sheet metal pressed type with an integral or separate flange or are of lightweight pressure cast aluminium.
What is the difference between B5 and B14 flange?
B5: Outer flange (flange diameter exceeds that of the motor) B14: Inner flange (flange diameter is smaller than that of the motor)
What is the main advantage of AC face motor mount?
The main benefit of an AC motor is its ability to produce constant torque up to the rated speed. The main components of an AC motor are the stator, stationary outer drum, and the rotor, the rotating inner portion attached to the motor shaft.
What is flange size in motor?
The flange diameter is smaller than the motor frame diameter. The holes are tapped. Available up to 160frame. The flange diameter is between B14A & B5 flange.
What does TC stand for on a motor frame?
• Totally Enclosed Fan Cooled (TEFC) enclosure. • NEMA TC-frame (C-face) and T-frame motors. • Cast iron frame with ribbed design for maximum cooling. • Solid full frame length cast iron mounting feet. • Steel fan cover.
What is C face motor?
C-Face Design:
Having a flat surface machined onto one side allows for direct-coupling with equipment while the weight of the motor is cantilevered with the help of a heavy duty flange. Of course, this method is not useful for large motors and is rare in HP ranges over 20HP. EXP(L): Explosion Resistant.
What does flange mount mean?
Flange Mount Bearings are bearing units contained inside a housing unit. The housing provides a rigid and secure position while allowing the bearing unit to rotate within a clean, contained environment.
What is B3 B5 mounting in motor?

| B7 Wall Mounted with Feet Right Hand Side when Viewed from Drive End | B8 Foot Mounted on Ceiling |
What is a B5 motor flange?
B5 – flange (‘D’ flange) The flange diameter is bigger than the motor frame diameter. The holes are not tapped. B5 flanges are available for all motor sizes.
What are the 3 types of AC motors?
The different types of AC motors are: Induction motors. Synchronous motors. Single-phase motors.
What are the 4 types of motors?
There are 4 main types of DC motors:
- Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux.
- Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current.
- Shunt DC Motors.
- Compound DC Motors.
How can I tell what frame my electric motor is?
The derivation of the two digit frame number is based on the shaft height in sixteenths of an inch. You can figure that a 48 frame motor will have a shaft height of 48 divided by 16 or 3 inches. Similarly, a 56 frame motor would have a shaft height of 3-1/2 inches.
What does FR mean on A motor?
Front engine, rear-wheel drive (FR)
– One of the earliest layouts in automotive design. The FR layout places the engine at the front of the vehicle and drives the power to the rear wheels via driveshaft and differential.
What does TENV stand for?
Totally Enclosed, and Non-Ventilated
Answer: Well – the answer is simply the motor is Totally Enclosed, and Non-Ventilated. Based on NEMA (National Electrical Manufacturers Association) definition, TENV states that the motor housing is fully enclosed and is not ventilated with a fan.
How do I know what flange I have?
You need to find the outer diameter, the inner diameter, the number of bolt holes, bolt hole diameter, and the bolt circle diameter. Bolt circle diameter (B.C.) is one of the most important measurements to make when identifying a flange.
Why is it called a flange?
From dialectal English flange (“to project”), flanch (“a projection”), from Old French flanche (“flank, side”). See flank. As a term for a group of baboons, it was popularized in the comedy TV series Not the Nine O’Clock News.
What is B5 flange?
What is F1 motor mounting?
On the other hand, the NEMA standard mounting position is referred to as F1, with the junction/conduit box located on the left side of the motor facing the output shaft. The design of most motors is such that they can usually be operated in many mounting positions, unless indicated otherwise.
Why is it called AC face motor?
The term is applied to a motor has feet or plate that the weight of the motor rests upon. The feet are commonly bolted to bottom of the motor body. Footless: This is the opposite of footed, which means these motors generally come with a C-face mount.
What are two types of AC motors?
But, AC Motors are classified into two types: Synchronous Motor. Induction Motors.
What are the 2 types of electric motor?
There are at least a dozen different types of electric motors, but there are two main classifications: alternating current (AC) or direct current (DC).
What are the 3 types of motor?
The types of Electric motors are available in three main segments like AC motor, DC motor, & special purpose motors.
Why frame size is important for a motor?
The frame size of a motor defines its mechanical interface to attached actuators. Motors of the same frame size can have different power, torque etc. but feature the same geometrical properties. The length of the motor housing is not affected by the frame size.
What does SFA mean on a motor?
Service Factor Amps, or S.F.A., represents the current the motor will draw when running at its full Service Factor. In the example nameplate, the S.F.A. is eight amps at 230 volts.
