Basic DC Gearmotor Data -Standard Part Numbers

1. This rating is for gearbox only. To determine output of any motor gearbox combination, multiply motor torque by the torque multiplier for that ratio. 2. Torque multiplier ratio is the gear ratio multiplied by its efficiency.

HOW TO SELECT A UNIT

The complete part number must include a standard HIL gearmotor part number (above) plus an applicable HIL armature dash number from the basic motor data chart (above). Use the following trial and error technique to start:

1. Assume motor speed of 4,000 RPM and divide it by the required output
speed to get approximate ratio.
2. From ratios charted above, select closest one.
3. Check maximum torque rating of that ratio with your actual requirement. Adjust ratio and motor speed up or down as needed.
4. Calculate output torque by multiplying motor torque by the "torque multiplier" of the ratio selected.
5. Select armature from voltage, load and speed required.

 

ORDERING

Order by standard part number (example: 276A224-4), making sure to include the armature dash number. Note any modifications as exceptions to the standard.
