Motor SIEMENS SIMOTICS DC Series 7

General Description

The SIMOTICS DC Siemens motor Series 7, shaft heights 355, 400 and 450 were developed using computer-aided design techniques. The thermal and magnetic utilization as well as the mechanical design are optimized. The rotor slots have been designed for low inductance and the main pole shape for uniform magnetic utilization. The result is a higher power density, perfect commutation and low-noise operation. The high-quality DURIGNIT 2000® insulation system and degrees of protection up to IP55 permit the motors to even be used in humid, tropical and aggressive industrial environments.
Computer-aided design and therefore optimization of the electromagnetic properties: For higher outputs and higher speeds.

Features

Extremely rugged components – for the toughest applications
Frame, bearing end shields and shafts of the motors are torsionally stiff and extremely rugged for
the highest mechanical smooth-running qualities up to vibration severity level SR in compliance withDIN EN 60034-14
use in the widest range of areas, e.g. grinding machines or rolling mills

Extremely Quiet

When designing the motor, we did everything we could to minimize the noise.
Just one example of many: The special main pole shape, which prevents magnetic force pulsations.
Another one: The optimized separately-driven fan.
Higher power density for low-noise operation.
Equipped for every application with IP23 and IP54 or IP55
MOTOR SIEMENS are available with degrees of protection IP23 and IP54 or IP55. This always guarantees the optimum solution – even under the toughest environmental conditions.

Customer Benefits

Low space requirements for innovative machine solutions High availability for cost-effective operation Low noise construction Extremely low vibrations and torque ripple

Application

Lift and cableway drives Rolling mill drives and winders Hoisting and travel gear drives for cranes Extruders in the plastics industry Drives for printing machines Drives for paper machines
