DC motor series PG350 with planetary gearbox

Torque: 1...12 kg-cm
speed: 8...990 rpm
Voltage: 12 a 24 V
Diameter: 35 mm
  • DC carbon-brush motor
  • It contains a filter to suppress electromagnetic interference
  • Bidirectional, the direction of rotation can be set by changing the polarity of the supply voltage
  • There is also a version with encoder
  • Planetary gearbox with metal gears (except first stage)
  • Only first stage is made of plastic for noise reduction purpose
  • Output shaft is supported by a ball bearing
