  • Re: RC car circuit

    When your car turns either way, the two motors have an oposite polarity to one another. Find the transistor outputs from the RF decoder that control the motors and XORthem; use the gate output to control a PWM before the DC BUS (e.g. 1=30%, 0=100%). You'll need basic skills in electronics.

  • Re: Windmill Synchronization

    Typically, grid connected wind turbines are now induction generators; they produce AC, not DC. You said DC, that's why I mentioned inverters. An Induction Generator is basically a standard AC motor that is driven by the wind to above synchronous speed which turns it into a generator inste...

  • Re: Non-Reversing vs. Reversing Contactor

    Hello wjwlitespeed I list the explanation below, for 3-phase squirrel-cage rotor motors. DC and single-phase forward/reverse contactor systems all have the mechanical/electrical interlock so that only one contactor switches supply power to the motor at any time.

  • Control Board Inside the PIM for GM's Old EV1 Car

    I am looking for detailed schematics for the control brd located inside the PIM of the ev1. The PIM is the box that uses 300Vdc input (from batteries/rectifier) and converts the DC into 3 phase variable frequency AC output, to run the main motor (inductive motor). I converts DC to AC by use of a 3 p...

  • Re: 1 Phase To 3 Phase

    hiii all, to be precise, simply, capacitors wont do the job. if one can design an RC phase shift oscillator for power frequencies, it would be fine since these oscillators are used only in the audio frequency range so far as i know. and again, a possible solution may be to give the single phase...

  • Re: Implementing a 1-Pole, 3-Way Switch Via Relay

    One last thing and I'll get off the subject. I have made a rough sketch of a wiring diagram for the system I described toyou. Look at it and see if there is anything you don't understand about it. I am assuming the your PC simply closes a contact through which you can run your control voltage (I...

  • Shoulder motor performance assessment in the sagittal plane in children with hemiplegia during single joint pointing tasks

    Background: Pointing is a motor task extensively used during daily life activities and it requires complex visuo-motor transformation to select the appropriate movement strategy. The study of invariant characteristics of human movements has led to several theories on how the brain solves the redundancy problem, but the application of these theories on children affected by hemiplegia is limited. This study aims at giving a quantitative assessment of the shoulder motor behaviour in children with hemiplegia during pointing tasks. Methods: Eight children with hemiplegia were involved in the study and were asked to perform movements on the sagittal plane with both arms, at low and high speed. Subject movements were recorded using an optoelectronic system; a 4-DOF model of children arm has been developed to calculate kinematic and dynamic variables. A set of evaluation indexes has been extracted in order to quantitatively assess whether and how children modify their motor control strategies when perform movements with the more affected or less affected arm. Results: In low speed movements, no differences can be seen in terms of movement duration and peak velocity between the More Affected arm (MA) and the Less Affected arm (LA), as well as in the main characteristics of movement kinematics and dynamics. As regards fast movements, remarkable differences in terms of strategies of motor control can be observed: while movements with LA did not show any significant difference in Dimensionless Jerk Index (JI) and Dimensionless Torque-change Cost index (TC) between the elevation and lowering phases, suggesting that motor control optimization is similar for movements performed with or against gravity, movements with MA showed a statistically significant increase of both JI and TC during lowering phase. Conclusions: Results suggest the presence of a different control strategy for fast movements in particular during lowering phase. Results suggest that motor control is not able to optimize Jerk and Torque-change cost functions in the same way when controls the two arms, suggesting that children with hemiplegia do not actively control MA lowering fast movements, in order to take advantage of the passive inertial body properties, rather than to attempt its optimal control.
