Information about DC Motor Drives

DC motor drives act as an interface between a controller and the motor. The drive must match the control signals (voltage and power levels) and signal type (analog or digital). The drive produces power conversion, amplification, and sequencing of waveform signals. Types of DC motor drives include adjustable or variable speed control, servo control, and integral motion control. Some drives are capable of delivering adjustable or variable speed control. Servomotors are generally small, powerful for their size, and easy to control. Integral motion control includes feedback and a controller. Important specifications to consider when searching for DC motor drives include considering whether or not a brushless DC motor drive or amplifier is needed. Some DC motor drives operate in conjunction with a brushless DC motor. Types of DC brushless motor drives include sine wave, trapezoidal, hall sensor commutation, and no sensor.

Products & Services Related to DC Motor Drives

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.

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.

Motor Speed Controllers

Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters.

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.
