Product Overview
Electric motors with squirrel cage rotor are used to drive pumps, fans, smoke exhausters and other mechanisms, which don’t demand rotational speed adjustment, and they are rated for continuous operating mode S1 from AC network, 50 Hz or 60Hz.
The motors meet the IEC requirements. The motors are manufactured for voltage 6000 V.
The motors are produced with frictionless bearings, with one shaft end. Outlet ends are brought out to the welded terminal box, unless undersize pressed box is specified when motor is being ordered.
Degree of protection for motors of: A series — motor IP23, output device- IP55.
Technical Parameters
Please answer the following questions, when placing the order.
1. Please specify any special requirements for noise. (Subject to IEC standard for noise limits.)
2. Please specify any special requirements for vibration. (Subject to IEC standard for vibration limits)
3. Please specify any special requirements for the number of starts.
(Standard: 2 starts under cold conditions, 1 start under hot conditions.)
4. Please specify the required direction of rotation.
(Standard: clockwise when viewed from the shaft extension end. For high-efficiency motors, the direction must be clearly indicated.)
5. Please specify the type of driven equipment. (e.g. fan, pump, blower, crusher, compressor, mill, etc.)
6. Please specify any special requirements for the load moment of inertia.
7. Please specify the type of drive system. (e.g. fluid coupling, gearbox, or direct connection.)
8. Please specify the type of coupling. (e.g. flexible coupling, belt pulley. If belt drive is used, please indicate the belt tension.)
9. Should an encoder interface be reserved on the motor?
10. Is the motor intended for operation at high altitude?
(Special design is required if the installation altitude exceeds 1000m a.s.l.)
11. Please specify the ambient operating temperature of the motor.
12. Will the motor be used in a humid tropical zone?
13. Will the motor be used outdoors?
14. Will the motor be used near the seaside?
15. Are there any anti-corrosion requirements?
(e.g. F1 – light corrosion, F2 – moderate corrosion, F3 – heavy corrosion.)
16. Please specify the bearing type.
(e.g. rolling or sliding bearings. Please also indicate brands if required)
17. Will the bearings be subjected to thrust load?
18. Is bearing insulation required?
19. Should the lubrication unit (oil station) be provided by us?
If yes, please indicate any special requirements.
20. Is the requested motor a spare motor? If so, please provide the drawing of the original motor.
21. Should the motor’s neutral point be brought out?
22. Are current transformers (CTs) required?
If yes, please specify the number and installation location (main terminal box or neutral terminal box).
23. Are vibration sensors required?
24. Are there any special requirements for temperature detectors?
25. Are there any special requirements for the squirrel-cage rotor material?
(e.g. cast aluminum, copper bar, trapezoidal copper bar.)
26. Is a double shaft extension required?
27. Please specify the position of the terminal box.
(Standard: on the right side when viewed from the shaft extension end.)
28. Please specify any special requirements for the maximum torque/rated torque ratio.
29. Please specify any special requirements for the starting torque/rated torque ratio.
30. Please specify any special requirements for the starting current/rated current ratio.
