Sealed, brushless 12- and 24-V dc SBL300 motors from Spal are suitable for axial fans and centrifugal blowers. The brushless, permanent-magnet design improves efficiency and reliability compared with electric machines using brushes that can wear out. Spal's rotors employ lightweight neodymium magnets and are designed to perform in high-temperature automotive applications including powertrain, battery, and HVAC. Fully sealed and dust-, water-, and vibration-resistant SBL300 motors are suitable for automotive, truck, bus, off-highway, and military applications. The motors' integrated-pulse-width modulation controls offer near-infinite variable speed control. Other benefits include built-in safety features, nonflammability, and reduced environmental impact. The SBL300 can be made as a single- or dual-shaft motor, customized to meet various needs.
