Sanyo Denki (Tokyo, Japan), a developer of cooling, power, servo and control systems to the computer, telecommunications, semiconductor, and motion control industries, added its new GV-type Series to its San Ace 40 family of compact dc cooling fan motors. Available in 12 V G-speed and J-speed models, the new San Ace 40GV measures 40 mm² x 28 mm (1.57 in x 1.1 in), making it suitable for use in 1U server units, data storage systems, copy machines, communications equipment, power supplies, and a variety of industrial equipment.
The San Ace 40GV's new design increases maximum airflow by as much as 15 percent over its predecessor (0.68 m³/minute, 24 CFM, 330 Pa/1.32 in H2O maximum) while consuming 15 percent less power (7.2 W). In addition, an advanced impeller and frame design allows the motor to operate 3 dB quieter than its competition. Coupled with its advanced performance features, the San Ace 40 GV offers a L10 life expectancy of 40,000 hours at 60 °C. The new cooling fan motor is also RoHS-compliant. Optional features on the San Ace 40GV include tachometer sensor and lock rotor sensor outputs, as well as pulse-width-modulation control, which permits the fan's rotational speed to be controlled in order to attenuate noise and power consumption.
