Stirrer Motors  Manufacturers, Traders, Suppliers

A large output torque, high
efficiency and minimal installation dimensions are the distinguishing
features of this spur gear unit.
Spur gear units with split-phase motors are used in machine
construction and precision engineering, such as conveyor belts, oil
skimmers, agitators etc.

Otto Huber GmbH supplies customers in the area of heating, plumbing and air-conditioning, and sewage technology. We also provide equipment for laboratory, analytical, and medical systems as well as special manufacturing systems engineering.

The motors are designed as AC motors with squirrel-cage rotor. The
M=f(n) characteristic is quadratic to the specific application. Due to
the use of special qualities of material and optimized electrical and
mechanical design, we attain a very high degree of efficiency with the
motors.

• Shaft height: 112 to 400 mm

The forced- and self-ventilated motors are, et al. used as pump motors
in vertical multi-stage process pumps. This application is characterized
by a quadratic load characteristic curve, high mechanical and thermal
requirements on the bearing, high motor speed and rough conditions of
use.
