Ideally, cooling fans, such as server fans, combine minimized size with a high rotation speed that ensures a high cooling capability. Toshiba’s new products adopt small packages that can be mounted on the limited board space of small motors. They also reduce the external component count with a one-sensor drive and current detection resistor-free system. One-sensor driving secures more reliable motor operation than a sensorless drive and reduces the number of hall sensors from three (required for a 3-sensor drive) to one. The current detection resistor-free system can reduce rated power supply and eliminate the large resistors previously required. These all contribute to reduced demand for space on wiring boards.
High speed rotation is achieved with a 150-degree commutation system. Rotation is faster and more stable than with a sine-wave commutation system, and vibration is lower than in a conventional 120-degree commutation system. Adoption of low on-resistance (upper + lower: 0.24Ω (typ.)) ensures suppression of heat generated from increased motor current by a high frequency drive, realizing support of a large current drive of up to 3A.
