YVF3 variable-frequency motor

YVF3-180M-2 is listed at 22 kW, 41.78 A and 163 kg. The catalogue’s 3,000 rpm heading is synchronous speed, not a measured loaded-shaft speed. Specify the required loaded rpm and torque with the inverter settings. A four-pole 180M entry is separately listed at 18.5 kW and 37.03 A; the frame designation alone does not identify the winding or output.

For horizontal frame 180, the two-pole bearing row lists 6211/C3 at both ends. The four-pole-and-above row instead lists 6311/C3 at the drive end and 6211/C3 at the non-drive end. The catalogue describes frame 180 and larger as relubricatable. Preserve pole count and mounting orientation when requesting bearings or a replacement motor; a common frame number is not a complete spare-parts specification.

The operating-conditions page states 220 V delta/380 V star for frames up to and including H280, and 380 V delta/660 V star above H280. Confirm the delivered winding and nameplate against the inverter output voltage. A 380 V supply statement alone does not tell an installer whether delta or star is appropriate.

The terminal table lists six main terminals with M6 studs, two M40 × 1.5 entries and a listed external cable-diameter range of 22–30 mm for frame 180. The top-mounted box has its standard cable entry on the right when viewed from the drive end and can rotate in 90° increments where installation clearance permits. Check cable bend space and gland compatibility in the machine layout.

The operating-conditions page gives −15°C to +40°C ambient and altitude below 1,000 m, with IP54/IP55 and IC411/IC416 configurations listed. Specify the actual enclosure and cooling option rather than treating both as simultaneous features. For condensation-prone locations, the catalogue describes an optional winding heater that is off while the motor runs and active when it is stopped; its circuit and interlock belong in the electrical scope.

Provide the full frame and pole suffix, power, supply and connection, minimum continuous and maximum speed, load profile, cooling choice, mounting drawing and auxiliary requirements. For an existing installation, include the terminal-box orientation and required bearing arrangement. That lets the supplier quote the motor and its necessary auxiliaries as one defined configuration.
