Siemens 6SN1146-1AB00-0BA1 Overview

The 6SN1146-1AB00-0BA1 is a type of AC motor produced by Siemens, a German manufacturing company that produces a wide range of products for various industries including automotive, aerospace, power generation, and electronics. The 6SN1146-1AB00-0BA1 is an infeed module, which is used to connect the drive group to the line supply. It is designed for use with machines that have few or short braking cycles, low braking energy, and limited dynamic demands, particularly for main spindle drives. It is also suitable for control cabinet designs optimized for low operating costs. These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry AC Motors from other manufacturers such as FANUC and Yaskawa.


This module is unregulated, which means that it does not have comprehensive overload protection. Instead, overload protection must be provided by the correct configuration and setting of current values in the control boards. When the motor brakes, the drive energy injected into the DC link is converted into heat in the braking resistors and dissipated to the environment. These braking resistors can be either integrated or mounted, and additional pulsed resistor modules (PR modules) may be used within certain limits to increase the braking energy capacity.

The 6SN1146-1AB00-0BA1 module is also equipped with an HFD reactor, which is a type of commutating reactor used in conjunction with the I/R module to form a step-up converter that controls the DC link voltage and enables regenerative feedback. This module is suitable for use with machines that have high dynamic requirements placed on their drives, frequent braking cycles, and high braking energy.


In addition to the infeed and HFD reactor, the 6SN1146-1AB00-0BA1 also includes an overvoltage limiting module, which limits transient overvoltage that may occur due to switching operations in the line supply. This helps to protect the system from damage due to voltage surges.

The 6SN1146-1AB00-0BA1 also includes a monitoring module, which contains a complete electronic power supply for the equipment bus and central monitoring functions for a separate drive group. It is used when the electronics power supply of the infeed module (I/R or UI module) is not sufficient for the number of drive modules in a group, or when drive modules are located in multiple cabinet compartments or tiers.

The I/R, UI, and monitoring modules of the 6SN1146-1AB00-0BA1 are typically located as the first module at the left in the drive group, and the mounting surface for these modules, as well as any commutating reactors and line filters, must be mounted to the mounting panels through a low-resistance connection. Line filters, line filter modules, and shielded cables are available to meet CE requirements for radio interference voltage limit values, and shield terminal plates are available to meet EMC requirements when using shielded power cables.

The 6SN1146-1AB00-0BA1 has an infeed power range of 5 to 10 kW, with a peak power of 10 kW and a charge limit of 1200 μF. It is cooled either internally or externally, depending on the specific application, and has a DC link power of 5 kW. It comes with a 2-year warranty from MRO Electric and is just one of many AC motor options available from Siemens and other manufacturers such as FANUC and Yaskawa.
