General description

Highest power rating, reliability, efficiency and modular cooling system:
This distinguishes the three-phase motors of the H-compact PLUS series.
These motors are available in shaft heights 450, 500, 560 mm with a gray cast iron enclosure, in degree of protection IP55 or IP23 - air or water cooled.
The insulation and bearing system guarantees the highest degree of reliability.
Siemens frequency converters and motors generates an efficient drive system for applications with constant torque and also with square-law countertorque characteristic.
The lifecycle costs are extremely important – and these make the H-compact PLUS motor so attractive.
H-compact PLUS motors save energy, require little maintenance and operate reliably over their long motor lifetime. An investment that pays back in a short time. H-compact PLUS motors are environmentally-friendly and can be recycled up to approx. 98 %.
