  • Low Cost Automation Tutorial: Introduction of Small Motor Characteristics
    mechanism design - 11: Introduction of small motor characteristics. Category : Drive mechanism design March12, 2010. Small motors can be categorized into: motors to obtain power by converting electrical energy to rotational energy, and motors for control where rotational position and velocity
  • Smart and small
    the high-frequency movement of the piezoelectric device, these valves were driven at up to 1 kHz by lower-power piezos. One of the prototype hybrid solid-fluid actuators CSA produced had a peak output power of 42 W at about 15 Hz. Magnets in Motion. More recently, hybrid actuators using magnetostrictive materials
  • High on Hypoids
    Trying to improve your overall efficiency? A high-efficiency NEMA premium motor helps only marginally if it is paired with an inefficient gearbox, such as a worm-gear drive. The motor is just half the equation - the gearbox is also critical. That's why, today, there is heightened interest in hypoid
  • DC Motors
    brake. Dc motor speed can be controlled smoothly down to zero, immediately followed by acceleration in the opposite direction -- without power circuit switching. And dc motors respond quickly to changes in control signals due to their high ratio of torque to inertia. Wound-field dc motors
  • Mighty motors
    and torque of the machine are estimated and two (hysteretic) loops are closed without the intermediate torque and flux producing current loops, which run at 25 &micor;sec. Their small size and high accuracy have, in the past, made permanent-magnet motors preferred for use in servo applications and computer
  • Stepping Motors
    , these new motors reach speeds of 5,000 to 10,000 steps/sec. Corresponding torques are 200 oz-in. to 3,100 oz-in. in 2 to 4-in.-diameter packages. Hybrid stepping motors also generally have high inertia (30 to 40,000 gm-cm2), small step angles (0.5 to 15 ) and high accuracy (+- 3%). Want to use
  • AC Motors
    starting current, and low slip. This design is built to obtain low locked-rotor current. Both locked-rotor and breakdown torque are low. Normally used where starting torque is low and where high overloads are not imposed after running speed is reached. Wound-rotor motors: Squirrel-cage motors
  • High-five to high-side current sensing
    through the meter. The technique was called high-side current sensing. However, high-side shunts require isolation in modern electronic control systems because of their direct connection to the high-side voltage rail. Current transformers perform this service in ac power systems. But the size and cost
