Siemens extends synchronous-reluctance drive systems

Tuesday, April 24th, 2018 von admin

Siemens is extending its portfolio of Simotics synchronous-reluctance motors to include the two new shaft heights, AH90 and AH225. With these new additions, the company is addressing calls from renowned manufacturers of pumps.

The motors are available in a power range of 0.55 to 45 kW, and now also with rated speeds of 1,500 and 3,000 min1. In conjunction with the recently launched Sinamics Reluctance Control License, precise encoderless closed-loop torque control is possible down to a standstill. The license enables field-oriented (vector) closed-loop control even when at a standstill – reliably eliminating the possibility of the synchronous motor “stalling” at any time even if the load inertia is not known.

KSB: High-efficiency motor with integrated frequency inverter

Wednesday, December 20th, 2017 von admin

Prototype demonstrates potentia: The KSB Group has finished the prototype of a super-compact high-efficiency motor with an integrated frequency inverter. The 22-kW synchronous reluctance motor is a prototype featuring new semiconductor technology that provides completely new cooling management for eliminating heat from power electronics.

By integrating the frequency inverter into the motor, developers were able to reduce the unit volume by over 25 percent compared with the traditional design.
