Need more power out of your gear motor? This is a high-power brushed DC motor that fits in the same form factor as used by the GM2/3/8/9 style gear motors.

## Pricing

- **Price:** $10.50 (inc GST) — $9.55 AUD, exc GST
- **Quantity discounts:** 10+ $9.16 (exc GST) · 25+ $8.87 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today; more stock is typically available with a 4–7 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-611:1` (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/POLOLU-611:1.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

**Note:** These are cheap, high-performance motors, so Pololu have notably low lifetimes, especially at higher voltages. Think of them as fireworks.

This high-power brushed DC motor fits in the GM2/3/8/9 series of gear motors, offering approximately 3 times the speed, twice the torque and quadruple the power-draw! Retrofitting the gear motor is easy – just remove the motor retainer strap, transfer the pinion gear, and reinstall – that’s it! This motor is popular for souping up anything driven by the more [standard 130-size motors](https://core-electronics.com.au/brushed-dc-motor-130-size-6v-11-5krpm-800ma-stall.html), such as flywheel NERF blasters.

**NOTE:** Be forewarned – we’re not kidding about the increase in power requirements and output! This motor eats batteries quickly, and it has a relatively short lifetime at high voltages. For example, in Pololu's tests, this motor was able to run continuously at 6 V without any load for approximately five hours before failing.
