The recently published IEEE 841-2021 has been improved and brought up to date with the latest standards. The standard defines the requirements for severe-duty totally enclosed squirrel cage polyphase induction motors (Figure 1) in the range from 0.75 kW to 370 kW (1 hp to 500 hp) up to 4000 volts. This is intended for applications where performance and reliability are critical. It reduces installation and operating costs and eliminates the need for end-users to develop their own internal specification. In addition to defining a reliable product, it supports the quick availability of these products in inventory.
