The BDCL1624 12V coreless motor is designed for compact industrial and robotic mechanisms requiring responsive brushless motion, combining a Ø16 × 24 mm body with 11,440 rpm rated speed, 1.54 mN·m rated torque, and optional magnetoelectric encoder integration for flexible OEM motion-control requirements.

The BDCL1624 12V coreless motor provides a compact brushless drive platform for applications that need moderate torque without increasing motor length significantly. The Ø16 × 24 mm body weighs 25 g, while the 12V winding delivers 11,440 rpm rated speed and 1.54 mN·m rated torque, making it suitable for compact industrial motion modules where size and controllability must remain balanced.
The same mechanical platform is available in 12V, 18V, and 24V windings, with rated torque reaching 1.78 mN·m on the 18V version. The dimensional drawing also shows Hall-sensored and sensorless motor arrangements, while an optional planetary gearbox and magnetoelectric encoder extend the platform for applications requiring gearing or additional feedback.
The three models use different winding configurations. Rated voltage, current demand, speed, torque, and driver capacity should therefore be evaluated as one operating set rather than treating the versions as interchangeable supply options.

The BDCL1624 should be integrated with particular attention to shaft loading, bearing selection, wiring space, and controller configuration. These factors can influence vibration, startup behavior, and long-term operating stability.
Shaft Load Limits
The bearing system supports a maximum dynamic axial load of 0.8 N and a maximum radial load of 8 N, measured 5 mm from the flange.
Bearing Selection
Both ball-bearing and sleeve-bearing options are available. Ball bearings may be preferred where radial stability and repeated operation are important, while sleeve bearings can be considered where the load and operating conditions allow.
Mechanical Clearance
Axial play is specified at 0.05–0.15 mm, while ball-bearing radial play is limited to 0.015 mm. Proper shaft alignment helps prevent unnecessary vibration and bearing stress.
Press-Fit Protection
Maximum static press-fit force is 10 N. Assembly force should not be transmitted incorrectly through the motor shaft or bearing structure.
Hall and Sensorless Configuration
The dimensional drawing identifies both Hall-sensored and sensorless rear configurations. Controller type, startup requirements, wiring space, and the final terminal arrangement should be confirmed when defining the motor configuration.
Operating Environment
Ambient temperature is specified from −20°C to +80°C, relative humidity should remain below 90% RH at 25°C, and rotor temperature should not exceed 85°C.
The BDCL1624 can be configured around the power supply, feedback architecture, mechanical transmission, and installation requirements of the OEM system.
| Customization Item | Available Options / Description |
|---|---|
| Winding Version | 12V, 18V, or 24V configuration |
| Control Configuration | Sensorless or Hall-sensor configuration can be reviewed according to controller requirements |
| Bearing Type | Ball bearing or sleeve bearing |
| Planetary Gearbox | Optional for reduced output speed and increased transmitted torque |
| Encoder Option | Optional magnetoelectric encoder for additional motion feedback |
| Cable Length | Can be adapted to installation and controller location |
| Connector Type | Connector format can be reviewed according to the OEM harness |
| Wire Sequence | Phase wiring can be customized |
| Shaft Interface | Shaft requirements can be reviewed for the driven mechanism |
| Prototype Configuration | Motor, feedback, bearing, and gearbox combination can be validated before production |
Cables, connectors, and wire sequence can be customized, while the final terminal configuration depends on the approved motor version.
The BDCL1624 is suited to compact systems where low motor inertia, brushless operation, and flexible control options are more important than very high output power.
Final selection should consider load inertia, acceleration requirement, supply voltage, driver current capacity, feedback method, and continuous operating time.
For compact brushless applications, the control architecture can matter as much as the motor dimensions. Startup load, winding choice, bearing configuration, Hall feedback, and gearbox requirements should all be resolved before the motor is finalized.
Germany | Industrial Automation Manufacturer
Application: compact rotary positioning module
Feedback: The 12V winding matched the existing controller architecture while the Ø16 × 24 mm body reduced the space required for the internal drive assembly.
Japan | Robotics Equipment OEM
Application: lightweight gripper mechanism
Feedback: The low-inertia brushless motor provided responsive movement during repeated open-close cycles without requiring a larger actuator frame.
United States | Precision Instrument Developer
Application: feedback-assisted adjustment mechanism
Feedback: The flexible sensor and encoder options allowed the motion architecture to be adapted as the prototype moved from basic speed control toward closed-loop operation.

A1: The choice depends on the controller and startup requirements. Hall feedback can be useful when rotor-position information and more defined startup behavior are required, while sensorless control reduces wiring complexity when the application and controller support reliable sensorless startup.
A2: The versions use different winding configurations. The 18V model is rated at 1.78 mN·m, compared with 1.54 mN·m for the 12V model, while their speed and current characteristics also differ. The best option therefore depends on the complete operating point.
A3: They serve different control purposes. Hall sensors are primarily associated with rotor-position information for brushless commutation and startup, while an encoder can provide additional motion feedback for speed or position control. The required combination depends on the controller architecture.
A4: Standard samples are typically prepared within 3–5 days, while bulk production normally requires approximately 20–30 days, subject to customization and the actual production schedule.
A5: Yes. The BDCL1618 uses a shorter Ø16 × 18 mm body and belongs to the 1–2W power class. It is better suited when axial installation space is the main constraint, while the BDCL1624 provides a longer platform with rated torque up to 1.78 mN·m.
