The FC1A / FC1B gearmotor consists of a gearbox with an aluminum alloy die cast case and a M51 synchronous motor working in clockwise (FC1A) and counter clockwise (FC1B) rotation senses. A large selection of reduction ratio is available (see tab Nr. 1 revolution time). Gears are made in self-lubricating composite material and/or in sintered metal to ensure a noiseless operation. The M51 is fixed to the gearbox with a removable bracket. The simple coupling allows a quick motor replacement. FC1A / FC1B gearmotors are available with bidirectional clutch on the output shaft (W10-W12).
