YZR crane motors: the duty cycle changes the rating you can use

A YZR wound-rotor motor is selected with its crane motion, rotor control and repeating load cycle. The same frame has different catalogue outputs at different duty factors; a short lift followed by cooling is not equivalent to frequent starts and electrical braking. Use the worked 200L-6 example below to prepare a motor-and-control enquiry.

One YZR200L-6, several duty-dependent ratings

The manufacturer’s table 8-2 lists the following values at 380 V. S3 duty uses a ten-minute cycle; the lower running speed at higher short-cycle output is part of the same table, not a different pole count. These entries are not interchangeable continuous ratings.

Duty entryOutput / speedStator / rotor current
S3 15% 33 kW / 950 rpm 69 A / 113 A
S3 25% 26 kW / 965 rpm 56 A / 86 A
S3 40% baseline 22 kW / 970 rpm 49 A / 72 A
S3 60% 19 kW / 975 rpm 45 A / 62 A
S3 100% table entry 17 kW / 978 rpm 42 A / 55 A
S2 30 minutes 26 kW / 965 rpm 56 A / 86 A

Describe the motion before choosing a duty column

Four minutes running is only an S3 example under the stated assumptions

At the catalogue’s ten-minute cycle, 40% corresponds to four minutes at load and six minutes off. S3 assumes starting does not materially affect heating. A crane with substantial acceleration losses cannot be sized from running time alone.

Include starts and electric braking explicitly

The manual distinguishes S4, which includes starting, and S5, which includes starting and electrical braking. Send starts per hour, acceleration and braking times, load torque through the motion and the inertia reflected to the motor shaft. Ask for the matching S4 or S5 rating rather than applying the 33 kW S3 15% entry to repeated hoisting.

Separate lifting from travelling duties

State whether this motor drives the hoist, trolley or bridge, and describe reversal, lowering and holding arrangements. The catalogue also contains YZRE brake motors; their brake-torque entries do not describe a plain YZR motor or establish the holding capacity of a complete hoist.

Match the rotor circuit and the mechanical replacement

Do not size the rotor circuit from stator current

For YZR200L-6 at S3 40%, the table gives 200 V rotor voltage and 72 A rotor current, alongside 380 V and 49 A on the stator. Give the control supplier the full motor sheet, rotor-resistance arrangement and switching sequence. The separately listed 26.6 A is no-load current, not the rotor-current rating.

Check the shaft and orientation, not just “frame 200”

The manual lists single tapered-shaft IM1003 for frames 180–400 and double tapered-shaft IM1004 in the same range. Its bearing table distinguishes IM1 and IM3 arrangements: frames 200/225 use a 6315 non-drive-end bearing in IM1, versus 7315AC in IM3. Send the existing mounting and shaft drawing before accepting an interchange.

Plan access to the brush gear

The brush table gives 32 × 12.5 × 50 mm brushes and a 140 mm slip-ring diameter for frames 200/225. Confirm the brush material, spring assembly and spare-part designation with the selected motor. Leave service access to inspect and replace the brushes instead of treating this as a maintenance-free cage motor.

Specify the actual crane environment

The manual separates general crane construction, IP44 with class F insulation and ambient up to 40°C, from metallurgical construction, IP54 with class H and ambient up to 60°C. State temperature, dust exposure and altitude; the stated altitude limit is 1,000 m. Do not assume the metallurgical construction is supplied on every YZR order.

CATALOGUE OVERVIEW

About this motor series

Xindali lists YZR wound-rotor three-phase induction motors for crane and metallurgical drives, with a published range of 1.5–710 kW and frames 112–560. Start selection with the hoisting duty, starts per hour, load cycle and control arrangement. Ask for the exact rotor circuit, brake interface and installation dimensions; the family listing is not a complete hoist drive specification.
