NUM AG motor Germany NUM AG model NUM AG price

NUM AG motor is a machine used to achieve mutual conversion between mechanical energy and AC electrical energy. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have a simple structure, are easy to manufacture, relatively robust, and can be easily made into high-speed, high-voltage, high-current, and large-capacity motors because they do not have commutators (see commutation of DC motors). The power coverage range of AC motors is very large, from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts. In the early 80s of the 20th century, the largest steam turbine generator had reached 1
