The Tangent Drive 1406 is a small brushless motor designed specifically for antweight combat robots using a tangent-drive drivetrain.<\/p>\n

The motor has a 5 mm knurled tangent-drive shaft designed to press directly into a suitable wheel. A carefully selected interference fit is important: too little and the wheel can slip on the shaft, while too much can place excessive load on the motor.<\/p>\n

It is designed for 2\u20134S LiPo batteries and weighs only around 13 g with the full-length wires, making it particularly attractive for lightweight antweight robots where both space and weight are limited.<\/p>\n

For an easier drivetrain setup, it can be paired with Repeat Drive Axles and a suitable AM32 brushless ESC.<\/p>\n

    Have you wanted to build a tangent drive robot? Normal drone motors make structure challenging because the shafts come out the side opposite the mount. Now with repeat tangent drive motors, the shaft comes out the side where the mounting is, making tangent drive easier than ever before! Pair with repeat drive axles to take all the complexity out of your super speed drivetrain! Use our Repeat AM32 dual brushless drive esc to get rid of the jitters and make your robot drive smoother than ever before!<\/p>\n<\/div>\n<\/div>\n
