Buy Shanghai engraving machine accessories, engraving machine manufacturers usually ask customers to choose what kind of configuration? For example, what kind of spindle motor demand, many large power requirements etc.. Customers and friends also understand, spindle motor is generally divided into stepping motor and servo motor. But many customers may not understand or don't understand, why the stepper motor stepper drive needs to work?
Stepper motor is a special motor control precision displacement and speed of the category, it is the rotation of the step angle inherent angle (determined by the mechanical structure of the rotor and stator) operation step by step, its characteristic is the rotation every step, step angle remains unchanged, and can keep the precision of the position. So no matter how many times the rotation, no accumulation of errors. Because the control method is simple, low cost, widely used in all kinds of open loop control.
Stepper motor operation demand of power electronic device the distribution of pulse drive, this is the stepping motor driver. Pulse signal it receives from the control system, according to the structural characteristics of stepping motor, pulse sequence distribution, control the angular displacement, rotation speed, rotation direction, brake loading state, the free state. The control system of each send a pulse signal, the driver can drive the stepper motor rotating a step angle. Stepper motor speed and the frequency of the pulse signal is proportional to the. The angular displacement and the pulse number. Stepper motor to stop rotating, can produce two kinds of state: brake loading can produce maximum holding torque or part (usually called the brakes to maintain, no electromagnetic brake or brake) and the rotor is in free state (which can be external thrust drive easy rotation). Stepper motor driver, must match with the step motor type. Otherwise, it will damage the stepping motor and actuator.
CNC engraving machine Shanghai engraving machine accessories according to customer demand production demand, choose the configuration, but the relative part of accessories bar Mei, or demand to engraving machine manufacturers hope, it can better play the engraving machine performance.
