This Design Idea combines a simple ISA-bus-resident interface circuit; a garden-variety PC; a high-resolution optical shaft encoder; and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor ...

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...

Many industries have delayed the use and adoption of sensorless FOC motor techniques because of the lack of motor control system knowledge, despite the many system benefits these techniques provide.

Oriental Motor of Japan is offering stepper motors with battery-free multi-turn absolute position encoding that can ride through power-loss. Oriental Motor of Japan is offering stepper motors with ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

From motor drives to data centers, an integrated approach is helping reduce complexity while improving responsiveness, ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

Encoders with a reduced package size can be a big help when space on and around the motor shaft gets tight. And suppliers have recognized that fact and developed new models that squeeze high ...

The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...
