Allied Motion's BL 48 series of 54 mm dia., 8 and 12 W small brushless DC motors are compact, yet incorporate integrated drive electronics. BL series motors are also available as motor-only models without drive electronics onboard (EE models). The BL48 series employs an external rotor and iron core stator to minimize cogging and maximize output torque. High quality components ensure BL motor life exceeds 20,000 hours. The BL48 series are a good choice for many types of small pumps, laser scanners, small fans and blowers, valve actuators and laboratory equipment. Features & Benefits As simple to control as a DC motor: 2-wire brushless design requires only a DC voltage to operate Reverse supply voltage protection Low EMI: Comply with EN55011, EN55022, EN500821 (with supply filter capacitor ) Low audible noise — ideal for use in noise sensitive applications Options Special shaft diameter and machining Square or customized mounting flange Higher protection level up to IP54 4-wire versions for speed sensing output and speed adjustment

Small precision 54 mm dia. brushless DC motors with integrated drive electronics (EB models) Rated at 8 or 12 W power output and 3000 RPM nominal speed Motor-only models without drive electronics available (EE models)
