This small stepping motor has a relatively high
torque/inertia ratio. Its design recognizes the
demand for small components to fit where space
is severely limited. The BAS series motor is available from stock in 5, 6, 12, and 24 volt models. They have a holding torque of 1.1 ounce-inch [7.8 mN-m]. All have a step angle of 18° or 20 steps per revolution. Applications are found in a wide range of medical and scientific instruments and robotics. These stepping motors are also recommended for low duty - cycle, battery operated equipment. |
