FAQs for  545 Planetary Gear Motor

Q1. Is this a 12V or 24V planetary gear motor? What voltage range does it support?

A: It’s designed to cover both common systems. The motor supports 8–26V DC, with typical builds around 12V and 24V depending on the winding and gear ratio. Share your supply voltage and target output RPM/torque, and we’ll match the correct winding/ratio.

Q2. Why choose a 545 planetary gear motor instead of a spur gear motor?

A: A planetary gearbox is typically selected when you need higher torque density, better load sharing, and a compact coaxial layout. It’s a practical choice for applications that see higher load, frequent starts/stops, or limited space for a larger gearbox.

Q3. What gear ratios are available, and how do I choose the right ratio?

A: The gearbox supports multiple stages and ratios (examples include 100:1 and 977:1, with a ratio range up to ~1/3736 depending on stages).

• Lower ratio → higher output speed, lower torque
• Higher ratio → lower speed, higher torque
  To choose quickly, start from your required output RPM under load and required torque, then verify current/thermal limits.

Q4. What torque can it provide?

A: Torque depends heavily on ratio and operating point. The page shows sample configurations with kg·cm-level output torque under load, and higher torque at stall. For proper sizing, use your real load torque + duty cycle (continuous vs intermittent), and avoid sizing to stall torque as a working point.

Q5. What are typical applications for this 545 planetary geared motor?

A: Common use cases include electric curtains, medical instruments, and ATM machines, plus other compact actuators that need stable torque at 12V/24V with a robust gearbox.
