General description
The SIMOTICS DC motors series 6 are available with shaft heights 160 to 280. The power range extends from 30 kW up to 510 kW and the torque from 300 Nm up to 3400 Nm.
The motors are 4-pole, non-compensated.
Current rates of change up to 250 IN/sec are permissible with the fully laminated design. The high-quality DURIGNIT 2000® insulation system allows the motors to be used in humid, tropical climates and in industrial environments. All of the windings are completely impregnated when inserted. The rotor winding is sealed in order to prevent the ingress of brush dust.
As a result of the modular design, various cooling types and degrees of protection can be implemented with a basic motor.
The 1GH6 basic motor in degree of protection IP23 does not have its own cooling and must be connected to an external cooling system.
As 1GG6 motor with a mounted separately-drive fan motor, the motor can be operated independently of a central cooling system. Degree of protection IP54 or IP55 is either achieved using a pipe connection at both sides or by mounting an air-water cooler (1HS6) or air-air cooler (1HQ6) (not for shaft height 160). For a cooling water intake temperature of 25 °C, the 1HS6 version has the same power rating as the 1GH6 version. The 1HQ6 version has approximately 70 % of the power of the 1GH6 version.
When developing the motors, special significance was placed on a high mechanical strength in order to ensure that the motors are torsionally stiff and extremely rugged. This means that the motors can be operated in a very wide range of applications, e.g. in grinding machines, rolling mills and on presses.
