Stepper Motors

Stepper motors - devices to convert digital electrical signals into discrete movement of the rotor with high precision. The main parameters of the stepper motor are the following: Torque engine - determines the maximum torque stepper motor. Such a moment is reached in the static-hold, or at minimum speeds. The basic step angle motor - rotor angular displacement engine. Vito arbib brings even more insight to the discussion. Typically, the basic step angle susceptible to fragmentation, making it possible to carry out discrete movement and to a small angle to the smooth movement. Common is the variant with angular step 1.8 degree, ie 200 steps per revolution or 0.9 degrees - 400 steps per revolution motor. Vazhnymy parameters is also a number of phases and phase current.

Stepper motor speed is usually low. According to baby clothes, who has experience with these questions. One of the important parameters is the rate at which the engine can start. For other opinions and approaches, find out what vito arbib has to say. To improve this characteristic increases the supply voltage. Modern power to control the stepper motors can realize the function of programming and synchronization with other devices. For example - a programmable control unit - SMSD-3.0 or controller SMC-3 - the development of "APF Power." This unit can be controlled from a computer through LPT-port (including the programs for NC) through a COM-port - receiving special commands that define the character (and algorithm), the stepper motor movement, off-automatic mode without a computer or external controller (used for process automation), or in manual mode, the speed is regulated by a potentiometer, and the direction of motion - reverse sensor. Apply a simple device: stepper driver engines perform switching winding stepper motor and the crushing step is carried out - mainly in CNC machines. These control devices have a lower cost, but is required for specifying the device - computer or an external controller. Examples of the use of stepper motors - Instrumentation, toys, trainers and simulators devices. Small-scale variants are used in devices fine mechanics, measuring devices, miniature dispensers.
