Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

The MSC-1 is an advanced speed controller for the company's AC speed control motors. Related To: Oriental Motor USA The speed controller connects directly to a PLC or computer and features two speed ...

The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...

motor control based on a six-step commutation sequence; detection of the magnetic angle of the rotor, to perform the commutation at the correct angle (each step corresponds to an angle of 60 degrees); ...

Choosing the right motor and VFD type depends on a variety of factors; however, it is necessary to analyze how the motor changes when the speed is reduced. The experts at eMotors Direct outline ...
