Brushless motor BD-1350

DC24 Vcompact

Product name
BD-1350 — DC motor for industrial/precision applications (Manufacturer: CITIZEN CHIBA PRECISION CO.,LTD.)

Overview
The BD-1350 is a compact 2-pole DC motor designed for precision industrial applications. It is specified with measurements taken using an aluminum heat sink (57×57×5t) mounted to the motor flange. Gearheads and magnetic incremental encoders are available as optional mounts. Standard BSD-36 Series drivers are factory-set to a 5,000 rpm maximum, with custom driver options available to permit operation above 5,000 rpm.

Notes and recommendations

• Performance values marked as measured are based on tests with an attached aluminum heat sink (57×57×5t); actual values depend on driver, encoder and mounting conditions.
• The BSD-36 Series standard driver is preset to a 5,000 rpm maximum; custom driver settings can allow operation above 5,000 rpm.
• When selecting gearhead ratios marked with an asterisk (*), verify the allowable output torque of the gearhead to avoid overload.
• For detailed performance graphs and interpretation, refer to the 'Detail of the Motor Characteristics'.
