Proper installation helps maintain stable performance, reduce vibration, and maximize motor service life during OEM integration.
Compact Mechanical Structure
The BDCM1230 features a Φ12 × 30 mm cylindrical housing, providing additional internal space compared with shorter models while maintaining a compact footprint for embedded systems.
Bearing & Shaft Protection
Axial play is 0.05–0.15 mm, with radial play ≤0.012 mm. Maximum dynamic axial load is 0.8 N, maximum radial load (5 mm from the flange) is 0.5 N, and maximum static press-fit force is 35 N. Proper shaft alignment helps prevent premature bearing wear.
Operating Environment
Recommended operating temperature is -20°C to +80°C, with relative humidity below 90% RH (25°C). Maximum rotor temperature should not exceed 85°C.

A1: Although precious metal brushed motors provide excellent low-voltage startup performance, starting reliability also depends on load inertia, power supply capability, and mechanical resistance. Matching the motor with the actual application load is essential for stable startup.
A2: Nominal speed is measured under rated conditions. In practical applications, supply voltage fluctuations, mechanical transmission losses, and load torque all affect the final operating speed.
A3: The BDCM1230 is better suited for applications requiring higher output power and greater torque reserve while maintaining a compact form factor. It offers additional performance margin without significantly increasing installation size.
A4: Yes. Samples are typically shipped via FedEx or DHL for fast delivery. Bulk orders can be arranged by air freight or sea freight depending on project requirements and destination.
A5: Yes. The BDCM1219 is recommended for applications where installation space and weight are more critical. Compared with the BDCM1230, it has a shorter Φ12 × 19 mm body while maintaining the advantages of a coreless precious metal brushed motor, making it suitable for ultra-compact OEM designs.
