Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters. Drive type describes the category of motor or system that is driven or controlled. Choices for alternating current (AC) products include induction motors, synchronous motors, pole number control drives, sensor-less vector drives, vector or feedback drives, and servos or brushless motors. Choices for direct current (DC) motors include brushed motors, brushless motors, and servomotors. Drive-type categories for stepper motors include unipolar stepper, bipolar stepper, permanent magnet stepper, variable reluctance stepper, and hybrid stepper. Full-step, half-step, mini-step and micro-step products are also available. Suppliers of motor speed controllers may also offer products for linear, voice coil, pneumatic, and hydraulic motors. |
Products & Services Related to Motor Speed Controllers
AC Motor Drives
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.
DC Motor Drives
DC motor drives act as the interface and power supply between a motion controller and a DC motor.
Motion Control Systems
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
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
Motor Controllers
Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry.
Servo Drives
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.
Stepper Motor Drives
Stepper motor drives power unipolar and bipolar stepper motors in full step, half step, and microstep motion control applications.
