The torque-enhanced hybrid stepper motor provides the best performance with maximum output torque. By designing the new magnetic circuit, using special materials and processes, the motor performance increases to the maximum, the output torque compared to the standard motor has been improved by 25 ~ 40%. It suits for the conditions as driver power for the customer has reached the limit that can not be increased, or the design space has been limited to death that can not choose a larger size of the motor but requires greater output torque at the same time.
