Advanced Notification of Interruption to Shipping
We are now expecting to move to our new premises in Rugby during the last week in November. During the move, we will not be shipping any orders out for the period Tuesday 25th November to Tuesday 2nd December. Last shipping day will be Monday 24th November and re-commence Wednesday 3rd December. Orders placed after 12 noon GMT on the 24th will be processed from the 3rd December
Whilst our machine shop is re-located, we are unable to carry out machining modifications on gears, sprockets, pulleys etc. Any order placed which includes machining options is unlikely to be processed until mid December.
The primary feature of this high-efficiency gear box is a worm gear, which locks the output shaft whenever the motor isn't turning. The high gear ratios of 216:1 or 336:1 make this gearbox appropriate for small walking robots, lifting mechanisms, and other applications where high torque is desired.
The motor is rated for 3 volts but will typically work fine up to 6 volts. When using this product with the dual serial motor controller (or any motor driver based on an H-bridge), keep in mind that up to a few volts (depending on the load) are lost on the transistors of the H-bridge, so that a 4.5 volt battery delivers about 3 volts to the motors, giving them a reasonable amount of power. Motor overheating can be caused by excessive stalling, even at very low voltages. We recommend that you use stall-detection sensors, or just watch your robot, to make sure that it doesn't stall for more than a few seconds at a time.
The 4mm, round output shaft is compatible only with Tamiya's sports and narrow tyre sets. See 'Which Wheel' tab for suitable wheels type 4P for a tight fit.
(Note: This gearbox uses the RE-260RA-2295 motor variant)
