Apparently, I'm a bit of an exception at my workplace: most of the engineers are hired directly to full-time, whereas I was hired through a recruitment firm (Aerotek) that they usually use mainly for the technicians (with the contract that I would be hired full-time after 6 months.)
I'm kind...
For my application, I desire continuous dc motor torque control - the command torque can go from -'ve to +'ve quickly.
I made a previous post here regarding bidirectional motor control - with some good suggestions- basically, I'm having a tough time measuring the load current in the h-bridge...
I'm trying to do bidirectional dc motor current (torque) control using resistors as the current sensor.
I'm using a bidirectional pwm/bridge IC combo (see www.solutionscubed.com), and I've tried the sense resistor placed between the bottom of the bridge and ground. It works well for PWM...
I know this topic has maybe been beaten to death, but nevertheless:
I have a dc motor in the lab, with a ratio=30 gear assembly, and tachometer attached to the rotor shaft.
For my application, I'm using it for torque (current control), using a fixed field.
This motor is intended for...
This isn't exactly motors related, but thought you guys might have some insight.
I'm trying to run some experiments on fault tolerant control for a dc motor torque control system with a torque sensor used as input for the current (torque) loop. Basically, this is an electric power steering...
1) relative cost of temperature sensor on armature of brushed dc motor.
2) Is Ra always proportional to temperature /temperature rise (besides, for instance, varying , slightly with other factors, such as brush resistance variation during commutation, and slow brush resistance wear over time)...
My question is regarding the brush of a separately excited dc motor, given in the context of the standard DC motor control model.
I am investigating whether the effective armature resistance (that is, the resistance due to the armature windings as well as the brush) varies during motor...
I want to run the Baldor vector drive ZD18H205–E in torque operating mode.
The induction motor I'm using it with is a M3538 (0.5 HP).
The only information I enter into the vector drive is the nameplate data on the motor. The unit performs calibration tests, and measures the input voltage...
As part of the knowledge I need for the torque limits for a hardware-in-the-loop simulation of an electric power steering system, I would like to know what typical steering ratios (ratio of how far you turn the steering wheel to how far the wheels turn) are for small-large sized sedan vehicles...
I am constructing a HIL simulation platform for a custom built EPS system.
Assist Motor + Driver
=====================
I need a 12V DC motor (brushed preferable), and driver/controller with up to 50-80A peak capability.
Now, I'm not that familiar with off-the-shelf products, but do any of the...
As part of my master's work, I'm setting up a HIL simulation of an EPS system-- previous work done by other students used a SIL simulation only.
My main barrier here is the Delphi EPS (made in 1999, used in the Fiat's) that we have in the lab (not sure where it came from...). Anyway, I can't...
