This is a set of wheelchair motors. They make great heavy duty robot motors. One left motor and one right motor (sold as a pair, we will not split the packages). They are right angle gear drives with a release (for free wheeling) and electric brakes on the motor. They are 24VDC and the operating speed is 135 RPM. As an option you can select for us to add encoders to the back of the motors. We use USDigital encoders part number E2-500-315-NE-D-G-1.
We recommend using one of the following motor controllers with this motor:
Due to the weight of these items, they do not qualify for free domestic shipping. (About 37lbs packed up.)
Interstate 12 Volt 35 Ah Sealed Lead Acid Battery (SLA). Nut and Bolt Fastener Lug.
This is a ANSI #40 sprocket that is custom bored to fit our wheelchair motors (link TD-111-135). We use these in most of our chain driven robots with wheelchair motors.
The InvenSense MPU-6050 sensor contains an accelerometer and a gyroscope in a single chip. It is very accurate, this sensor is used in self balancing robots, drones, smartphones, etc. The sensor uses the I2C-bus to interface with microcontroller.
