Allied Motion's BL 58 series of 68 mm dia., 35 and 50 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 BL 58 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 BL 58 series are a good choice for many types of small pumps, scanners, small fans and blowers, and document/currency handling equipment. Features & Benefits As simple to control as a DC motor: 2-wire brushless design requires only a DC voltage to operate Adjustable speed and direction selection Thermal overload protection with automatic recovery 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 IP67DS

Small precision 68 mm dia. brushless DC motors with integrated drive electronics (EB models) Models rated at 35 and 50 W power output and up to 4000 RPM nominal speed Motor-only models without drive electronics available (EE models)
