Tips: Reasons and solutions for reduction in torque frequency characteristic of the stepper motor

The relationship between output torque and control pulse of stepper motor is called torque frequency characteristic.
Feature: By taking the maximum load torque (start torque), the rotational velocity of the stepper motor will be increased gradually but the load capacity is reduced along with the increase in pulse frequency.
The reasons for the reduction in torque frequency characteristic of the stepper motor:

Influence of winding inductance: It takes certain time to rise and reduce the current in winding. When the pulse frequency is low, it can realize long power-on cycle of winding, large average value of current, high energy that can be obtained for the motor and high torque that can be maintained. However, when the pulse frequency is high, it can realize short power-on cycle of winding, small average value of current, little energy that can be obtained for the motor and reduction in torque that can be maintained.
Iron loss: Along with the rising frequency, the rotational velocity of the rotor is increased. Due to additional rotational EMF generated in rotor winding, the motor faces larger resistance torque and the eddy loss of iron core is also increased.

Measures for improving the high frequency of torque characteristic through two ways:

Resistance can be increased by reducing the time constant. To ensure the current in live current is not changed, it is also necessary to increase the power voltage while increasing the resistance.
Improve working mode. Adopt multi-phase exciting working mode. Due to the multi-phase exciting working mode, the power-on time for each phase is prolonged, then more energy can be obtained for the motor so that the output torque is increased.

Strong nema 34 stepper motor

I bought 3 stepper motors in ATO. It's a great deal for quality nema 34 stepper motors. The cables that come with each motor are quite robust. For these applications that I need, they work perfectly.
