If you are comparing 775 planetary gear motors by ratio and output torque, this guide explains the key terms and selection logic:
775 gear motor basics (definition, specs and selection)
IND-42GMP775 is a Ø42mm 775 planetary gear motor built for applications that need a larger frame size than micro gearmotors but still require compact reduction. The motor body length is 66mm and the operating voltage range is 8–25V DC, which covers common 12V and 24V drive systems in actuators and portable equipment.
This page includes two reference configurations (5:1 and 125:1) with no-load, on-load and stall figures for comparison. The gearbox sheet lists the stage length options and the available ratio families by stage, so the mechanical design can be checked together with the target output speed and torque. In practice, ratio selection should be done from the working point (required output rpm, torque, duty cycle, and temperature condition), not from stall torque alone.
Typical applications include security products, smart home modules, medical devices, personal care products, and power tools. For mechanisms with hard end-stops or frequent start/stop cycles, current limiting in the driver is recommended to avoid extended stall events.
For OEM supply, shaft geometry, wiring length, connector type, and adding a pinion/gear can be configured. Encoder integration can be evaluated when feedback is required.
Start with target output rpm and required torque, then check duty cycle and temperature rise. Lower ratios keep higher output speed with less torque multiplication. Higher ratios reduce speed and increase available torque, but can increase load on the gearbox at end-stops. Share your working point and we will recommend the stage/ratio.
They are reference values from sample configurations. Actual output depends on your working condition (load, duty cycle, temperature, driver control). For procurement, we can align a specific configuration and define a test method and acceptance window.
A 775 gear motor is a 775 DC motor combined with a gearbox (planetary or spur) to reduce speed and increase usable output torque. If you need a quick explanation before selecting ratio and working point, read:
