AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals.
|
|
AC motors include single, multiphase, universal, induction, synchronous, and gear motors. They also include servomotors.
|
|
AC servomotors are responsive, high-acceleration motors typically constructed as permanent magnet synchronous motors.
|
|
Amplifier and comparator chips are board-level components for amplifying voltage, current, or power.
|
|
DC motor drives act as the interface and power supply between a motion controller and a DC motor.
|
|
Gate drivers are electronic circuits that apply correct power levels to metal-oxide field-effect transistors (MOSFETs) and insulated gate bipolar transistors (IGBTs).
|
|
Motion control systems contain matched components such as controllers, motor drives, motors, encoders, user interfaces and software. Components in these systems are optimally matched by the manufacturer.
|
|
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
|
|
Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. PWM amplifiers have a much higher power capability for a given volume than linear amplifiers. They are also less expensive.
|
|
Servo drives provide electrical drive outputs to servo motors in closed-loop motion control systems where position feedback and corrective signals optimize position and speed accuracy.
|
|
Signal transformers transfer information from one circuit to another by electromagnetic induction. They are used to increase or decrease the voltage from one side of a power transformer to the other.
|
|
Stepper motor drives power unipolar and bipolar stepper motors in full step, half step, and microstep motion control applications.
|
|
Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.
