What free servo controller used for brush DC motor 400W ?

Is a four-pole DC motor mixed excitation
I have three of the DC motor.
Technical characteristics:
Supply voltage, 27 ± 10%
Current consumption, no more than 23 A
Power, W 400
Speed, r / min
9000
9600
7600
Hours of operation: long-term (continuous)
Dimensions mm: 107x181 (no fan)
Weight, kg, not more than: 3.5 kg (no fan)

According to my calculations - needs 16-18A continuous current for the operation, for 400W power on the shaft.

The site Uli, http://www.uhu-servo.de/servo_en/UHU% 20FAQ_en.pdf
I found the information that the controller:
"Q: What are the current limits of the UHU controller?
A: The limit is not the controller but the power circuit and the PCB. The common design with IRF540N MosFets
does up to 60 V and 20 A, the IRFP260N Version does up to 120V and 35 A. "

The project servo Elm-Chan (and other variations Elm) I not found max power (A, V), to which it was designed. Or is it better to use the HP UHU (High power) is as more modernized version.

Can I use the scheme servo drive on axis x, y.
And on the z-axis use stepper motor is?
Then from the third motor, can make the spindle.

Will I be able to do without reduction gear to reduce engine speed. And instead use PWM.

Power will be sufficient for cutting and machining aluminum.
Thank you in advance for your answers.

You will probably not get 400W of power from the motor if you do not use gear reduction. The torque is quite low, but it can run fast. Gear it down.

Keep in mind that nema 23 steppers typically put out less than 80W of mechanical power. That's more than enough for typical machines.

What do you mean by Free servo controller? the AMC shown in the link for DC brushed motor should be OK, but analogue input signal.
For max. rpm you need to find out the voltage/1Krpm, to find out what you need for the maximum shown.

To: H500
I want to use a belt gear with a gear ratio of 1:3, 1:4, 1:5. My approximate scheme is illustrated.
Encoder will be on the driven shaft.
Yeah, collect all based on NEMA 23 is comfortable, and do not need to invent himself complexity.
But, I still want to try to make a servo motor drive.
Options For information on the calculation and it'll post later.
Ideally with a minimum center distance up to 250 mm. And on the drive pulley diameter 15 teeth, slave 60.
However, not all manufacturers recommend it.
From the descriptions of most sites, and documentation on the calculation pulley, drive - at least on the drive between 15 and 26 teeth.
Belt type SM3, SM5, Step 5, which runs up to 40,000 thousand rev / min and power up to 5 kW.
I will try to test UHU chip and charge of its implementation.

To: Al_The_Man
I mean cheaper. open "code", open circuit assembly.
Cost of a good servo driver for my dc motor is 200-250 dollars. The cheapest I found is $ 160 - Duangdong.
For example, the project cost me UHU 50-100 dollars.

Time has passed since my first post about the servo amplifier (driver).
I began to search for possible solutions to create it.
I bought one of the previously popular chips on the controller.
But, I realized that I can not control,
develop the setup,
increase the power of the servo amplifier,
independently develop PCB.

If I buy or to solder a circuit board controller based on MDL-BDC 24 (TI) or something like that, I can put together your own servo amplifier?
I understand the standard firmware or topology, may not ideal.
But still, for the start of it help me?

I'm talking about kit's (starter set) to help yourself, to understand motor control.

Thank you.

You need to describe the application, servo motion (CNC) or velocity control etc?

Ok.
Control of the cnc machine via Mach3, or turbo CNC, art cam
At the name whale, as I understood, it is designed for robots (motion engine robots), industrial applications, factory automation devices and systems, household appliances, and etc.
Kit is designed for the movement of brush DC motors.
Based on the description of the whale, it goes to the standard firmware and software for calibration.
Brief description of module.
Quiet control of brushed DC motors with 15 kHz PWM frequency
Three options for open-loop voltage control
– Industry-standard R-C servo type (PWM) interface
– Controller Area Network (CAN) interface
– RS232 serial interface
Controller Area Network (CAN) interface or RS232 serial
interface for closed-loop, speed, position, or current control
CAN communication
– Full configurability of module options
– Real-time monitoring of current, voltage, speed, and
other parameters
– Load firmware over RS232/CAN
Power motor 12V, 24V.
Nominal current motor 40A max
Description states that the electronic board keeps inrush current motor 60A - up to two seconds.

Meaning of the idea is this:
Choose a simple brush motor up to 100W (for example, 3000 rev / min., 5A, 12V, 24V).
Download official standard firmware in the controller.
Connect the encoder (eg, 200 pulses) to the engine.
Connect the cables and power supply.
Start software, Mach3, or turbo CNC, art cam for example,
Configure basic settings (speed, current, etc.).
And test it at work, with the basic standard firmware.
It's like starting the experiment.

The controller appears to be Canopen or similar, do you intend controlling in a CNC environment with Mach?
Not sure if Mach does a network control?
The ideal is use in Torque (current) mode.
