                                High Torque Stepping Motors

Torque is the amount of rotational force that a motor generates during operation.In a given application,the torque for each axis is defined by the specific requirement in the machine,which is required to move the object driven by the motor.The torque requirement of the axis determines the size of the motor and any gearing necessary.

TT Motor’s engineers aim to optimize the torque output of the motor during the design phase. The key components involved in 

torque production of the motor are the magnet, the winding and the flux path. The energy content of the magnet drives the 

strength of the motor but a balance must be achieved between power and cost. Also, the higher the number of pole pairs in the 

magnet, is the higher the amount of torque for the same dissipated power. High torque stepper motors are an example of this, 

as they have a higher number of pole pairs for a given motor size.TT Motor’s engineers optimize the design based on the 

physical size, energy content, pole pair count and geometry of the magnet.


Copper content of the winding contributes to the power provided by the motor. Striking the right balance is important for 

creating high torque stepper motors that can maximize torque without drawing a tremendous amount of power. Flux path guides 

all of the magnetic field in the usable channel, minimizing losses. A high torque stepper motor that produces high power but has 

high losses does not benefit the application. Understanding the complete motor design allows TT Motor’s engineers to pack the 

most power possible into the smallest motor package.
