Quick answer
For an elevator motor enquiry in Bangladesh, send more than a model name. Useful information includes the motor nameplate, lift capacity and speed, controller model, encoder details, brake arrangement and clear photos of the installed equipment. These details help narrow down the correct replacement.
Motor fundamentals
What does the elevator motor actually do?
In a traction elevator, the motor provides the turning force used by the traction system to move the car and counterweight. It works as part of a larger system with the drive, controller, brake, encoder or feedback device, sheave and suspension arrangement.
02
Works with the VVVF drive
The motor and drive must be suitable for each other so motion can be controlled correctly.
03
Uses position or speed feedback
Many modern systems use an encoder or similar feedback device for controlled motor operation.
04
Works with the brake
The brake arrangement is an important part of the complete traction system and must be considered during replacement.
Buyer terminology
Motor, gearless motor and traction machine: what is the difference?
These terms are often used together in lift enquiries, but they do not always describe exactly the same scope. Knowing what you actually need helps avoid ordering the wrong component.
Elevator motor
The electrical machine that produces rotational force. Depending on the elevator design, the motor may be part of a geared or gearless traction arrangement.
Gearless motor
A gearless arrangement drives the traction sheave without a conventional reduction gearbox between the motor and sheave.
PMSM motor
PMSM means permanent magnet synchronous motor. This motor technology is commonly associated with modern gearless elevator traction systems.
Traction machine
This normally refers to the wider machine assembly rather than only the motor. Depending on the design, it can include the motor, traction sheave, brake and associated mechanical components.
Need the complete machine assembly rather than only motor-related information?
See our elevator traction machine page.
Replacement matching
What should be checked before choosing a replacement lift motor?
A similar-looking motor is not enough. The replacement has to fit the elevator's mechanical arrangement and work with its electrical and control system.
Motor identity
Manufacturer, model, serial or type information from the original nameplate.
Electrical rating
Relevant voltage, current, power and other nameplate data should be recorded.
Lift duty
Lift capacity, travel speed and system configuration affect motor selection.
Controller & drive
The motor needs to work with the installed controller and VVVF drive arrangement.
Encoder
Feedback type, interface and installation arrangement may need to match.
Brake
Brake configuration and electrical/mechanical requirements need checking.
Sheave & ropes
Sheave dimensions, grooves and suspension arrangement matter when the wider machine is involved.
Physical installation
Mounting, dimensions, shaft position and available installation space must suit the project.
System context
The motor cannot be selected in isolation
A traction motor works with several other parts of the elevator. If one of those interfaces is different, a replacement motor may need additional engineering work or may not be suitable at all.
- VVVF drive and motor parameters
- Controller and feedback arrangement
- Encoder type and connection
- Brake voltage and configuration
- Traction sheave and suspension system
- Mounting position and structural support
For drive-specific information, see the elevator VVVF inverter page.
Repair or replacement?
A motor problem should be diagnosed before a new motor is ordered
Noise, vibration, overheating, starting problems or drive faults do not automatically prove that the motor itself must be replaced. The wider lift system should be checked first.
Record the actual symptom
Note what happens during starting, travel, stopping or brake operation. Record available drive or controller fault information.
Inspect the related system
Motor condition should be considered together with power supply, drive, encoder, brake, bearings, wiring and mechanical loading.
Identify the installed motor
Photograph the complete unit and nameplate. Record controller and inverter information as well.
Decide the repair scope
The appropriate next step may involve repair, a component change, full motor replacement or wider modernization depending on the confirmed fault.
Match and commission the replacement
A replacement needs correct mechanical installation, electrical connection, drive setup and testing before normal elevator operation.
Motor-related components
A motor enquiry may involve more than the motor body
The required scope depends on the actual equipment and fault. Photos and part information help establish whether the enquiry concerns the complete motor or a related component.
Encoder / feedback
Motor-position or speed feedback component where applicable.
Brake assembly
Brake components form part of the traction-machine arrangement.
Bearings
Bearing condition can affect noise, vibration and mechanical performance.
Sheave assembly
Relevant when the enquiry covers the complete gearless machine.
Motor wiring
Connections and cable condition should be inspected as part of diagnosis.
Drive interface
Motor parameters and feedback need to suit the installed VVVF system.
For components outside the motor family, browse elevator spare parts.
Price factors
What affects elevator motor price in Bangladesh?
There is no useful single motor price without knowing the required equipment. A quotation should be based on the actual motor and project requirements.
Motor type
Geared, gearless and PMSM arrangements involve different equipment and requirements.
Motor rating
Power and electrical requirements influence the required motor configuration.
Lift duty
Capacity, speed and suspension arrangement affect selection.
Encoder & brake
The required feedback and brake configuration can change the replacement scope.
Controller compatibility
Existing controller and VVVF drive details need to be considered.
Supply vs installation
Component supply alone is different from replacement, setup and commissioning work.
A low price for the wrong motor is not a saving. Confirm the technical match before comparing final quotations.

Buyer questions
Elevator motor FAQs
What is a gearless elevator motor?
A gearless elevator motor is used in a traction arrangement where the motor drives the traction sheave without a conventional reduction gearbox between them.
What is a PMSM elevator motor?
PMSM means permanent magnet synchronous motor. It is a motor technology commonly used in modern gearless elevator traction systems.
Can I buy a replacement motor using only the kW rating?
No. The power rating is only one part of motor selection. Lift capacity and speed, controller and drive requirements, encoder, brake, mounting and mechanical arrangement may also need to match.
What information is most useful for identifying an old lift motor?
Start with clear photos of the complete motor and its nameplate. Controller, VVVF drive, encoder and brake information is also useful when checking a replacement.
Is the elevator motor the same as the traction machine?
Not exactly. The motor is the electrical machine that produces torque. The traction machine normally describes a wider assembly that can also include the traction sheave, brake and related mechanical components.
Does every motor fault mean the motor needs replacement?
No. Some symptoms can come from the drive, encoder, brake, bearings, wiring, electrical supply or other parts of the elevator. The cause should be checked before ordering a replacement motor.
What affects lift motor price in Bangladesh?
Motor type, electrical rating, lift duty, encoder and brake arrangement, controller compatibility, required accessories and whether installation or commissioning is included can all affect the final quotation.
Can a gearless motor be used during elevator modernization?
It may be part of a modernization plan, but the existing lift, controller, drive, shaft arrangement, suspension system and project requirements need technical assessment before the final scope is selected.
