12V Coreless Motor Ø16×24 mm Industrial Brushless DC Motor 1.54 mN·m | BDCL1624 BODENMOTION

Overview of BDCL1624 12V Coreless Motor

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.

Key Features of BDCL1624 Industrial Brushless DC Motor

• Compact Ø16 × 24 mm Construction – Fits embedded industrial and robotic mechanisms where both motor diameter and axial space are limited.
• 12V Rated Performance – The 12V winding provides 11,440 rpm rated speed and 1.54 mN·m rated torque for compact DC-powered systems.
• Torque up to 1.78 mN·m – The 18V winding offers the highest rated torque within the series for applications needing additional load margin.
• Low Rotor Inertia – Rotor inertia of 0.36 g·cm² supports responsive acceleration and rapid speed changes.
• Three Voltage Platforms – 12V, 18V, and 24V versions allow the motor to be matched to different industrial power architectures.
• Brushless Drive Structure – Electronic commutation removes mechanical brush wear and supports long-term operation in repeated motion applications.
• Hall-Sensor or Sensorless Layout – The motor drawing provides configurations for both Hall-sensored and sensorless integration, allowing the control architecture to be selected according to application requirements.
• Optional Gearbox and Encoder – A planetary gearbox and magnetoelectric encoder are available when lower output speed, higher transmitted torque, or additional motion feedback is needed.

Technical Specifications of BDCL1624 12V Coreless Motor

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.

Motor Model Number Breakdown

Mechanical Design & Installation Notes for Brushless DC Motor with Hall Sensor

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.

OEM Customization Options for BDCL1624 Industrial Brushless DC Motor

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

Application Fields of BDCL1624 Brushless Motor for Robotics

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.

• Compact Robotic Joints – Provides responsive rotary motion for lightweight secondary joints and adjustment axes.
• Robotic Grippers – Drives finger, linkage, or adjustment mechanisms where compact dimensions and repeatable motion are required.
• Industrial Positioning Modules – Supports indexing, adjustment, and controlled rotary movement in embedded automation assemblies.
• Optical & Inspection Equipment – Provides smooth motion for focusing, scanning, and precision adjustment mechanisms.
• Medical & Laboratory Equipment – Fits compact internal drives requiring low maintenance and controlled movement.
• Encoder-Assisted Actuators – Can be combined with the optional magnetoelectric encoder when additional speed or position feedback is required.

Final selection should consider load inertia, acceleration requirement, supply voltage, driver current capacity, feedback method, and continuous operating time.

Why Choose BODENMOTION for Your 12V Coreless Motor Project

FAQ – BDCL1624 Industrial Brushless DC Motor

Q1: Should the Hall-sensor or sensorless configuration be selected?

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.

Q2: Why is the 18V version rated for more torque than the 12V version?

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.

Q3: Can the optional encoder replace the Hall sensors?

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.

Q4: What is the typical production lead time?

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.

Q5: Is there a shorter 16 mm brushless alternative?

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.
