FAQ
•Can motors be wound for 60 Hz or non-standard voltages?
Yes. Standard production is 380 V 50 Hz, but plants wind for 400, 415, 440 or 660 V and for 60 Hz networks to order. State the exact grid parameters and whether the motor will run on a variable frequency drive; the factory adjusts the design and documents performance at your frequency in the test report.
•Will a Russian motor mount in place of my existing IEC machine?
In most cases yes: GOST frame sizes correspond to IEC frames, and mounting arrangements use the same IM code system. Send the frame size, shaft height and mounting code of the existing machine; the supplier returns a dimension sheet for direct comparison so your fitters confirm bolt-down compatibility before ordering.
•What replaces a failed motor in an old Soviet-built plant?
Often the same series, still in production or manufactured as a direct successor. Provide the nameplate data — series, frame, power, speed — and suppliers identify the current equivalent. This is a routine request from factories in Central Asia, Africa, the Middle East and Cuba operating legacy equipment, and it avoids costly re-engineering of mounts and couplings.
•How are large generators and turbogenerators inspected before shipment?
Large machines undergo factory acceptance testing against the contract programme: winding resistance, insulation, no-load and, where facilities allow, load runs. Buyers or their inspectors may witness tests in person or by video. Reports, preservation procedures and transport bracing are documented, and supervision of installation can be contracted separately.
•What lead times apply for motors and valve actuators?
Small and medium asynchronous motors of popular ratings ship from stock or within 2–4 weeks. Special windings, high voltage machines and explosion-proof versions take 8–16 weeks. Valve actuators typically run 4–8 weeks including factory setting to your valve data. Sea freight adds 25–45 days depending on destination.
