Asynchronous vectorial motors
Official Partner:
Vector asynchronous motors are specially designed to achieve small dimensions and high performance in variable speed applications with vector type controllers. In particular, these motors, although significantly more compact, achieve very high specific power ratings compared to a standard motor with the same shaft height. The special electromagnetic and mechanical design allows operation in constant power mode at maximum speeds of up to 8000 rpm.
