What do I need to calculate stepper motor torque?
I need the calculation to determine the stepper motor torque to find the load that it can withstand in horizontal position using a lead screw at 1/2″ diameter with 13 TPI.
How much weight can my stepping motor lift?
There are two main questions that we can answer with respect to motor torque and the mechanical advantage of lead screws, 1) What torque motor do you need to lift a particular weight, or 2) What maximum weight will my motor torque be able to lift. This formula uses Newtons (N) as it’s final unit.
Which is the start / stop region of a step motor?
B. Start/Stop region: the region in which a stepping motor can be directly started or stopped. C. Slew Range: the motor cannot be started directly in this area. It must be started in the start/stop region first and then accelerated to this area. In this area, the motor can not be directly stopped, either. Otherwise this will lead to losing-step.
How does inertia affect the speed of a step motor?
Because of the inertia of rotation the Pull- Out Torque is always larger than the Pull-In Torque. The torque meeded to accelerate the system inertia is often larger than the friction torque of the load. This limits how quickly the load can be accelerated. performance of a stepping motor is constant at low speeds.
How can I rotate a cylinder around its axis?
I have a solid cylinder (shaft) that I want to rotate around its axis. The cylinder is supported by two bearings at its ends. No other loads than the weight are applied to the cylinder. I already know how to calculate the torque required to start rotating the cylinder up to the desired speed within the required time.
How much torque do you need to rotate a cylinder?
Required torque to rotate a solid cylinder around its axis. I’m a mechanical engineer and I am more specialized in structural calculations than dynamic calculations and now I’m faced with a basic dynamic problem and would need some help.
What are the variables that affect the torque of a motor?
Torque. Known variables: Weight (lbs), Outer Diameter (ft), Inner Diameter (ft), Change in Speed (RPM), and Time to accelerate Total System (sec) In addition to the torque required to drive the load at a steady speed, torque is required to accelerate the load.
