Description

This gearmotor consists of a high-power, 12V brushed DC motor combined with a 74.83:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 3591.84 counts per revolution of the gearbox’s output shaft. The gearmotor is cylindrical, with a diameter just under 25mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5mm from the face plate of the gearbox.

Key specs at 12V: 130 RPM and 300 mA free-run, 240 oz-in (17 kg-cm) and 5.6 A stall.

These cylindrical brushed DC gearmotors are available in a wide range of gear ratios and with five different motors (two power levels of 6V motors and three power levels of 12V motors). The gearmotors all have the same 25 mm diameter case and 4 mm diameter gearbox output shaft, so it is generally easy to swap one version for another if your design requirements change (though the length of the gearbox tends to increase with the gear ratio). All versions are also available with an integrated 48 CPR quadrature encoder on the motor shaft.

Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. For these gearboxes, the recommended upper limit for instantaneous torque is 200 oz-in (15kg-cm); we strongly advise keeping applied loads well under this limit. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes, especially for the versions that use high-power (HP) motors; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

Features

  • Gear ratio: 74.83:1
  • Free-run speed @ 6V: 65rpm
  • Stall current @ 6V: 2800mA
    (this motor will run at 6V but is intended for operation at 12V)
  • Stall torque @ 6V: 120oz·in
  • Free-run speed @ 12V: 130rpm
  • Free-run current @ 12V: 300mA
  • Stall current @ 12V: 5600mA
  • Stall torque @ 12V: 240oz·in
    (this is a theoretical value; stalling the gearbox output shaft is likely to damage the gearbox)
  • Lead length: 8 in
    (may vary by a few inches)
  • Motor type: 5.6A stall @ 12V (HP 12V)
  • Encoders: YES
  • Size: 25D x 66Lmm
  • Weight: 104g
  • Shaft diameter: 4mm
