Allied Motion's BL 70 series of 69 mm dia., 85, 95 and 110 W small brushless DC motors are compact high power density motors that incorporate integrated drive electronics. BL series motors are also available as motor-only models without drive electronics onboard (EE models). The BL 70 series employs an internal rare-earth magnet rotor and advanced iron core stator designed to maximize torque density. High quality components ensure BL motor life exceeds 20,000 hours. The BL 70 series are a good choice for many types of fluid and gas pumps, material handling equipment, 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 69 mm dia. brushless DC motors with integrated drive electronics (EB models) Models rated at 85, 95, and 110 W power output and up to 3800 RPM nominal speed Motor-only models without drive electronics available (EE models)
