Hybrid Linear Stepper Motor Signal Module
Hybrid Linear Stepper Motor Signal module
How to control the direction of rotation of hybrid linear stepper motor?
When your controller (host) sends a double pulse (ie positive and negative pulse) or the amplitude of the pulse signal does not match, we need to use our signal module to convert to 5V single pulse (pulse plus direction).
A. Enter the double pulse
The DIP switch of the signal module should be set to the "double pulse" position. When the positive pulse, the motor is running; when the negative pulse, the motor reversal. Positive and negative pulses can not be given at the same time, the specific timing can refer to the signal module manual.
B. The DIP switch for the single pulse signal module should be set to the "single pulse" position. When there is a pulse output motor rotation, change the direction of the signal level can change the direction of the motor rotation. Specific timing can refer to the signal module manual. Some basic concepts of hybrid linear stepper motors:
Motor inherent step angle:
Refers to the control system for each step pulse signal, the motor rotation angle, such as HB-20S2001 motor gives a value of 1.8 ° (that the whole step is 1.8 °, the half of the work is 0.9 °) , This step angle can be called 'motor inherent step angle', but this is not necessarily the actual work of the motor when the real step angle, the real step angle is related to the drive.
Number of mixed linear stepper motors:
Refers to the number of coils inside the motor, the current commonly used two-phase, three-phase, four-phase, five-phase hybrid linear stepper motor. Motor phase is different, the step angle is also different, the general two-phase motor step angle of 1.8 °, three-phase 1.5 °, five-phase 0.72 °. In the absence of subdivision drive, the user mainly by choosing a different number of mixed linear stepper motor to meet their requirements from the pitch angle. If you use a subdivision drive, the 'number of phases' will become meaningless, and the user can change the pitch angle by simply changing the fineness on the drive.
Holding torque (HOLDING TORQUE):
Refers to the hybrid linear stepper motor power is turned, but no rotation, the stator locked rotor torque. It is one of the most important parameters of a hybrid linear stepper motor. Normally the hybrid linear stepper motor approaches the torque at low speed. Since the output torque of the hybrid linear stepper motor is constantly attenuated with increasing speed and the output power also varies with increasing speed, keeping the torque becomes one of the most important parameters of the hybrid linear stepper motor The For example, when people say 2N.m hybrid linear stepper motor, in the absence of special instructions is to maintain the torque of 2N.m hybrid linear stepper motor.
