01 / Applications
Define the motion.
Build the motor specification.
Choose the application, then coordinate actual speed, starting behavior, operating cycle and the driven machine. Final ratings follow the proposed motor model.
Hoist Motors
Record load, hook speed, reeving, starts and lowering/braking duty. Coordinate motor speed, gearbox ratio and the holding system.
Trolley Travel Motors
Specify moving mass, wheel arrangement, speed, acceleration and drive count. Review cooling and inverter duty at low speed.
Long-Travel Motors
Share crane mass, travel speed, wheel/driven-wheel arrangement, gradient and outdoor conditions for the drive review.
02 / Duty & control
The working cycle matters.
The complete drive matters too.
Bring the mechanical and electrical data together before comparing motor ratings. Specify the functions and accessories the application needs.
Load & actual speed
Use hook speed for hoisting and linear travel speed for CT/LT. Include gearbox ratio, reeving, driven-wheel arrangement and external transmission.
Starts & operating cycle
Record ED, starts per hour, load cycle, acceleration, lowering and ambient conditions. Simple factors do not verify the thermal rating.
VFD or pole-changing
Coordinate the voltage/frequency, actual speed range, motor/inverter compatibility and low-speed cooling requirements.
Brake, feedback & mounting
Share shaft/flange/foot dimensions, brake requirements, encoder interface, thermal sensors and terminal-box orientation.
03 / Configure & plan
Build the motor enquiry.
Make the assumptions visible.
Record operating data and accessory requests. Review the separate power reference alongside the original budget comparison. Neither calculation selects a motor, brake or thermal duty rating.
Your Motor Configuration
Sample values are for discussion. Hoist speed means hook speed; travel mass means the moving crane/trolley mass. Add drive count and actual transmission data in the notes.

03 / Supply & environment

04 / Supply request
Options, quantity & target timing
Options and IP ratings require model confirmation. Target timing is a request, not confirmed delivery. Brake, encoder, thermal sensors and cooling require motor/control compatibility review.
04 / Technical scope
Motor, control and duty.
One coordinated package.
Review the source specification areas against the proposed motor. Efficiency, duty, protection and accessories require model-specific confirmation.
| Types | Squirrel-cage induction motors for hoist / trolley / long-travel; wound-rotor requirements subject to supply confirmation. |
|---|---|
| Standards | Project requirements may refer to IEC 60034, FEM duty guidance and ISO 281 bearing-life calculations. Confirm applicable editions, evidence and scope in the proposal; this page establishes no compliance. |
| Efficiency | IE2 / IE3 request directions; actual efficiency class, applicability and available evidence confirmed per model. |
| Insulation & Protection | Class F/H and IP55–IP65 requests, confirmed for the actual motor and installation. |
| Voltage | 380–460V, 50/60Hz, 3-phase |
| Duty | S3/S4 motor-duty requests and M4–M6 mechanism-duty information are reviewed separately. Do not assume an automatic equivalence between motor duty, M class and FEM group. |
| Options | DC disc brake, encoder, PTC/PT100, forced ventilation, space heater, tropicalization |
| Accessories | Brake rectifier, terminal box rotation, special shafts, paint systems |
The selectable values record requirements. Neither the simplified multiplier nor the power list verifies a motor frame, S3/S4 rating, efficiency class, braking capability or compliance.
05 / Motor references
See the arrangement.
Define the application.
Existing website images provide a starting reference for motor and crane-drive layouts. They do not establish the exact model, rating or a verified customer installation.
Motor and hoist product display
Website reference. Confirm exact motor, installation and supplied accessories.
Crane trolley and hoist-drive layout
Website reference. Confirm exact motor, installation and supplied accessories.
Travel motor and mounting arrangement
Website reference. Confirm exact motor, installation and supplied accessories.
06 / Project steps
From operating data
to an agreed motor package.
Define the application, review the model and agree the inspection and supply scope before delivery.
Sizing
Load/mass, speed, operating duty and environment.
Proposal
Review power, frame, control, interfaces and budget.
Manufacture
Confirm winding, assembly and inspection scope.
Testing
Agree electrical, run and brake/control checks.
Delivery
Confirm drawings, documentation and packing.
07 / Before you specify
Planning a motor
replacement or new build?
Actual duty, speed and interfaces guide the selected model.
Discuss My Motor Requirements ↗What information helps identify a replacement motor?
Send motor/gearbox nameplates, mounting and shaft dimensions, actual operating speed, voltage/frequency, control method and the working cycle. Include the brake, encoder, sensors and installation environment.
Why does the budget comparison differ from the separate hoist-power reference?
The original budget divides hoist power by rope falls. At a given hook speed, reeving reduces rope force while increasing rope speed, so that division can understate motor power. The separate reference does not divide by falls. The original budget remains visible only for comparison and does not price a verified motor.
Does the listed kW band select a motor?
No. It is a comparison with the original discrete list, not a catalogue frame, approved rating or motor selection. If the reference exceeds 200 kW, no next band is invented. Actual mechanical and thermal selection requires project data.
Is 1.8 times motor torque a brake selection?
No. The retained illustration assumes 1450 rpm and uses the original budget kW basis. Actual holding and dynamic braking depend on brake location, gearing, load, inertia, closing behavior and duty. The illustration does not establish a minimum rated brake.
How are travel power and brake requests handled?
Travel power uses rolling resistance only and omits acceleration, gradients, wind and drive sharing. A travel brake request is recorded, but the original travel price branch adds no brake cost. Its actual supply scope needs a separate quotation.
Does the calculator verify duty, efficiency or delivery?
No. M-class/ED/start/ambient factors are illustrative, and S3/S4 duty, efficiency class, insulation, IP rating and inverter compatibility require actual motor review. The quantity budget is EXW and timing choices are requests; final price and delivery need confirmation.
08 / Technical & commercial enquiry
