## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ROB-15277:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ROB-15277:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This is a simple ~140RPM (no load), DC planetary gearmotor. This motor is great for various applications such as robotics, electric locks, household automation, and small actuators.

The supply voltage range is 6VDC - 24VDC with the polarity maker at the base of the motor. The planetary gear box, mounted on top of the motor housing, gives this motor a relatively large stall torque for its size. The overall body of the motor is made of metal, with the exception of the set of planet gears on the first input gear set, which are plastic.

This planetary gearmotor has an over all body dimension of 76.1mm length with a 22mm diameter while the drive shaft is 12mm in length and 6mm in diameter.
