Electric motor mounting types.

Electrical induction motors synchronous speed the speed at which an induction motor operates depends on the input power. The table lists the most common installation methods in relation to the mounting position. It is standard to see the frame size on every electric motor nameplate but do you understand what that frame means in regard to the mounting of the motor many have been in the situation where you needed a specific frame only to realize it was made with a special shaft or has a mounting flange but no one knew how to find this information. Electric motor bases and mounts are mounting bases that are designed to make work on electric motors simpler and easier.

It has high starting torque and large overload capacity. Motors designated 56h have two sets of 2f mounting holes 3 and 5. The actual motor mounting may influence the protection class and bearing design. Flange mounted electric motors need further specification of the required pitch circle diameter of the fixing holes in the flange ff or ft type of flange dimension m.

Slip ring induction motor. These bases help to simplify proper belt tensioning during initial motor installation. Type motor mount style adaptable motor. Discontinued nema frame.

Certain nema 56z frame motors have 1 2 x 1 1 2 long shaft with 3 64 flat. Standard short shaft for direct drive applications. The specified mounting is to be mentioned when ordering an electric motor. Built from tough materials including steel rubber and more bases and mounts are built to last while making later maintenance checks.

Base of 56hz frame motors has holes and slots to match nema 56 56h 143t and 145t mounting dimensions. Motor flange table quick reference of typical motor sizes at motor technology we strive to supply standard product for any application you may have. Whether you re an installer engineer or maintainer this is a must have reference. Don t just assume you can bolt any motor in any orientation.

With reference to standard iec 34 7 the electric motor s nameplate must be marked with the mounting position imb3. Type motor mount style adaptable motor mounts material steel nema frame 213 215. Motor mounting arrangements iec standard 60034 7. The speed of slip ring induction motor can be changed up to 50 of its normal speed.

Slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts pumps winding machines printing presses line shafts elevators and compressors etc. Electric motor efficiency calculate electric motor efficiency. Below is a visual reference of typical electric motor mounting positions. Compatibility of differing motors becomes a major issue when you are looking for a replacement.
