Miniature brushless DC motor with integral drive electronicsMclennan Servo Supplies is releasing a new miniature brushless DC motor with integral drive electronics for precision speed control. It is manufactured by Allied Motion/Premotec of the Netherlands. Measuring just 32mm diameter with a nominal length of 42mm, the compact BL30 EB delivers an output torque of 30mNm at 3500rpm with an 11W power output rating. The motor's outer rotor design ensures minimal cogging, and a high-load bearing system and IP54 sealing make it suitable for small pumps, laser scanning heads, fans, medical devices and other applications where compact design, long life and high performance are essential.

An integrated speed control loop with a speed-set input enables adjustment of the motor speed from 200 to 5000rpm. Available in CW and CCW variants for either a 12V DC or 24V DC supply, a two-wire version operates from a simple DC voltage and the four-wire alternative includes an 18 pulse per rev tachometer output for speed monitoring. The motor complies fully with EN 55014 for EMC, and protection is included for reverse supply voltage and thermal overload with automatic recovery.

The BL30 EB is supplied with a 4mm diameter, 12.5mm long output shaft as standard with a front-face spigot mounting with M3 fixing holes. Customised versions are available with special shaft modifications, alternative flange mounting, custom leads and connector configurations, as well as rear-mounted encoders and gearbox options.

As with all motion control components and equipment supplied by Mclennan, the BL30 EB is available for evaluation from stock. The mechatronic specialist is also able to offer customised rotary and linear positioning assemblies based around the new motor using its own design, manufacturing and distribution capability.
