- the type HB stepping motor

the type HB stepping motor advantages: high resolution (General step torque Angle of 1. 8 degrees more), large torque, compared with type multiphase HB stepping motor, drive power tube amount is much, but the price is cheap.
disadvantages: large special low speed vibration, 60 RPM attachment of large noise, easy to produce resonance, high speed compare with multiphase HB type, half step into the large torque ripple, when the phase synchronization of torque Angle compared with multiphase motor, stepping motor coil impedance. When high speed torque is small.
