Industrial equipment multinationals Siemens is expanding its portfolio of Simotics synchronous reluctance motors with the new AH90 and AH225 shaft heights, addressing the requests from well-known manufacturers of pumps, fans, compressors and machine builders for different shaft heights
A power range between 0.55 kW and 45 kW and now also available with rated speeds of 1 500 min-1 and 3 000 min-1. In conjunction with the recently introduced Sinamics Reluctance Control License, precise encoderless torque control is possible until standstill. The license enables a field-oriented (vector) control even at standstill – the possibility that the synchronous motor dies at any time, even if load inertia is not known, is thus safely excluded.
How digitization is the key to speed Siemens has equipped the motors and converters with a data matrix code. This code, which is attached to the motor housing and to the housing of the display or inverter, gives the user at a glance access to technical data, spare parts information and operating instructions. The data are accessed using a mobile terminal and the Simotics Digital Data App for motors or alternatively the Siemens Industry Online Support App for converters.
The availability of two-dimensional or three-dimensional design data results in shorter, more flexible design and engineering processes
As an integrated drive system, Simotics reluctance motors and Sinamics converters are specially matched. Compared to asynchronous motors, they offer highly efficient operation, especially in the partial load range. The coordinated system, consisting of Sinamics G120 converter and synchronous reluctance motor, enables the ideal control of pumps, fans and compressors
The combination of the Sinamics S120 converter and the Sinamics Reluctance Control license even enables encoderless control to a standstill so that applications in connection with reels, servo pumps and extruders are possible.
Synchronous reluctance drives operate with exceptional energy efficiency and at the same time offer greater power reserves than a comparable asynchronous drive.
with conventional asynchronous technology, Siemens with its Simotics synchronous reluctance motors enables extremely high efficiency at the rated operating point and in the partial load range with simultaneously high power density and dynamics. The result is cost and energy efficiency.
Synchronous reluctance drive technology has proven very successful in countless practical applications in this field. Customers such as machine manufacturer Olbrich, gypsum board manufacturer Knauf and compressor manufacturer Kaeser Kompressoren have opted for the engine code
due to their energy efficiency and optimal operating behavior due to synchronous encoderless operation and their easy commissioning with synchronous reluctance drives for synchronous drives.
