April 21, 2016 - The Simotics DP crane motors are based on the Siemens 1LE1 platform. The gray cast iron motors have been specifically designed to withstand the high-humidity, salt-laden air encountered in container ports. Combined with the Sinamics S120 converter family, they can be used in all typical applications to shift and lift heavy loads. Due to the high power density, compact dimensions are possible.
Simotics crane motors have efficient components for cost-optimized operation, and the converter achieves efficiency class IES1/IES2. The motors perform their tasks in hoisting, trolley, slewing, luffing and traversing gear. The range of product sizes runs from shaft height AH132 to AH315L. Both non-ventilated and ventilated designs are available for the intermittent duty typical for cranes.
Simotics crane motors are based on the 1LE1 platform for standard Simotics family motors. Certain common components, such as stators, rotors and enclosures, are standardized. The motors have the same dimensions, but different versions are created by, for example, using different winding variants and mechanical add-on parts. The use of active parts for high efficiencies helps save energy in converter operation.
The high power density enables powers ranging from 1.1 kW to 481 kW to be achieved with all common voltages and torques ranging from 10 to 4,600 Nm. The motors have a high overload capability, and a wide range of speed control from 730 to 1,730 rpm. A high overload capability, in some cases up to 450 percent, provides large torque reserves to cope with high surge loads.
Special protective measures against humidity, such as high-quality paint systems and corrosion protection in the motor interior, ensure a long service life in typical seaport air. The concept includes permanent lubrication systems with long intervals between bearing relubrication, providing motor protection up to 40°C, and with options for even higher ambient temperatures, as well as against air humidity of up to 100 percent, and salt-laden air.
