High-Torque PKP Series Stepper Motors
After revising the magnetic design and structure design of the PKP Series, it products much more torque than the conventional motors of the same size. In addition, torque can be increased in the high-speed range by using high current motors.
Reduced Power Consumption and Heat Output
If the running current of a PKP Series stepper motor is decreased and the motor is operated at the same torque as the PK Series standard type, current consumption and heat output can be reduced.
Characteristics Diagrams of Decreased Running Current in PKP Series Stepper Motors
Power Consumption Reduced by 20% (at low speed)
Comparison of driver power consumption when low speed torque is tailored to the PK Series standard type stepper motor.
Temperature Increases of 10°C (18°F) and More are Suppressed
Comparison of stepper motor surface heat output when low-speed torque is tailored to the PK Series standard type
The PKP Series stepper motors provide torque equivalent to a stepper motor of the next larger frame size, contributing to downsizing of equipment.
Flat and lightweight design. The motor can be installed in a narrow space by being flatter.

Utilizing Hybrid Stepper Motor Technology
A hybrid stepper motor is a combination of the variable reluctance and permanent magnet type motors. The rotor of a hybrid stepper motor is axially magnetized like a permanent magnet stepper motor, and the stator is electromagnetically energized like a variable reluctance stepper motor. Both the stator and rotor are multi-toothed.
A hybrid stepper motor has an axially magnetized rotor, meaning one end is magnetized as a north pole, and the other end a south pole. Toothed rotor cups are placed on each end of the magnet, and the cups are offset by half of a tooth pitch.
