PAINTING
Our standard range of motors are painted with a gray protective paint according to RAL 7031(grey). Other colours are also availableupon customer requests.

FEET
For QS type motors (63-132 frames), feet can be mounted on three sides, permitting terminal box assembly on the desired side. For QU types (160-250 frames), feet are detachable and this feature provides flexibility for different mounting types.

TERMINAL BOX
Motors frame size 63-200 have terminal boxes on top close to the drive end which can be turned 90, so that conduits can be at each side. For the other frame sizes, it is on top and close to the drive end.

CONDENSATION HOLES
In the basic design, motors are supplied without holes. In case of customer requests, motors can be supplied with drain holes. Since these motors are provided with a special plug in the hole, the degree of protection remains IP 55.

VOLTAGE / 60 Hz
Motors are normally designed for 400V, 50Hz. Other voltages and 60Hz frequency are optional. Our motors wound for 50Hz can be operated on 60Hz for the same output power. The ratios given below indicate changes in the given parameters.

Calculations are based on 20,000h (L10aah) bearing life time and the actual values will differ if
radial and axial loads act at the same time. Mechanical strength of the endshields should
also be considered for critical applications.

Value of force Fr acting on any point of the shaft end (between points X=max and X=0) may
be calculated according to the following formula:


Where;
Fx0 - value of Fr force acting on the beginning of the shaft end
Fxmax - value of Fr force acting on the shaft end
E - length of the shaft end
