Kacperek - Model IE1 Engines -Three-Phase Motors
The mechanical size of the engine. The mechanical size of the motor is the dimension from the motor axis to the plane of the motor base (mounting feet). This dimension is often called a motor lift. The mechanical size corresponds to the constant diameters of the rollers. Induction motors of alternating current and some direct currents have standardized motor connections, e.g. The 0,37-1400 engine will definitely have a diameter shaft fi14 and one of the 3 motor flanges B14 B14B or B5. The most popular collars on the market are B5 and B14. Motors with such flanges are available in large quantities from the warehouse. B14B medium flanges sometimes called B14 / 1 are less popular.
Sometimes it happens that engines with the same horsepower and speed come in two different sizes. These smaller ones are referred to as motors in a reinforced housing. They are standard in a larger housing, but they are also available in a small version.
When placing an order or request for quotation, specify the motor connection specifying the mechanical size and flange size, eg 71B14 or by providing a motor connection: flange diameter and shaft diameter of the 105 / 14 motor
The table below shows which motors are present in a given mechanical size. It allows you to identify the engine.
Transmission and motor connection - measurements
The transmission connection defines the diameter of the hole in the drive axis and the diameter of the collar. The motor connection defines the diameter of the shaft and the diameter of the flange. In order for the transmission to be connected to a given motor, its connection must match the motor connection, which means that the diameters of the gearbox and motor shaft have to be of the same diameter and the diameters of the flanges must have the same diameters. It happens that a gear with a smaller shaft is fitted with a gear opening with one degree more, using a so-called reduction sleeve. However, motor flanges must have absolutely identical diameters. Reduction sleeves are widely used to speed up the order.
