A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
For example, if, in addition to reaching with the arm, the hand must be controlled to grab an object, an efference copy of the arm motor command can be input into a forward model to estimate the arm's predicted trajectory. With this information, the controller can then generate the appropriate motor command telling the hand to grab the object.
An implementation is described in a whitepaper by Zilog on an ebike hub motor controller [5] for a 200 W, 24 V brushless DC electric (BLDC) motor. [ 6 ] P.A.S or PAS may appear within the list of components of electric conversion kits for bicycles, which implies Pedal Assistance Sensor or sometimes Pulse Pedal Assistance Sensor .
The 361 cu in B engine also introduced in 1958 was essentially the same as the 350 except with a larger 4 + 1 ⁄ 8 in (105 mm; 4.12 in) bore, for an actual displacement of 360.83 cu in (5,913 cc). In 1962, the Dodge Polara 500 came standard with a 305 bhp (227 kW) version of the 361 that had a four-barrel carburetor , dual-point distributor ...
A piezoelectric motor or piezo motor is a type of electric motor based upon the change in shape of a piezoelectric material when an electric field is applied. Piezoelectric motors make use of the converse piezoelectric effect whereby the material produces acoustic or ultrasonic vibrations to produce linear or rotary motion. [ 85 ]
Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...
The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines.Engines in the O-360 series produce between 145 and 225 hp (110 and 170 kW), with the basic O-360 producing 180 hp (130 kW).
In 1961, California regulations required that all new cars be sold with a PCV system, therefore representing the first implementation of a vehicle emissions control device. [ 6 ] Starting with the 1963 model year, most new cars sold in the U.S. were so equipped by voluntary industry action so as to avoid having to make multiple state-specific ...
