If you are looking for genuine raw power to move large objects along linear paths, this NEMA 42 Stepper Motor is the ideal choice for the job. Offering an incredible holding torque of 30Nm, or, there are few motors that can provide as much power as this one can.

Thanks to the sheer rotational force that this stepper motor can offer, it is designed for extremely heavy loads, such as moving heavy production cameras or large loads of rubble and other materials along a linear path. The holding torque is also capable of maintaining around 3 tons, allowing it to even hold up a small truck if the task so requires it. This ensures that, almost regardless of the load you are eager to hold or move, the Nema 42 is more than capable of taking on the challenge you present it with.

In terms of physical specifications, the frame size of this motor is 110 x 100mm with a body length of 201mm and a total weight of 11.7kg. The shaft length is 55.37mm while the shaft diameter is 19mm, with an extra spine running along it to increase grip. This is an important feature for a motor this powerful, as extreme weight would typically cause motors to slip and possibly burn out. Fortunately, this stepper motor is designed to be utilised for extreme loads, making it a great choice for applications in which a very heavy load needs to be moved along a linear path – while even offering precision accuracy due to the 1.8° step angle.
