Overview
Option 1: with DC +12V Reference Motor Board (Delivery condition)
Option 2: Customer Motor at individual DC +5..48V
Block Diagram
NOTES:
- 12V to 5V DCDC
- DClink voltage ADC is also isolated !!! I I think it is best to: rename the "Current ADC" to "Isolated ADC" they do measure from current sensor and have internal isolation
- From J17 there are 2 1-wire buses to J16, on one of them there is in parallel the temp sensor
Main Components
- MOSFET drivers für 3-phase für BLDC / EC- Motors
- Current measurement for 2-phases, extendable to 3 phase measerement
- Remperature sensor on board and 1-Wire bus external option
- Encoder inputs for three differential or single ended signals
Key Features
- Motor Evaluation with a FPGA controller board, recommended with the Digilent Arty Z7 board
- Quick evaluation with reference motor board
- Power option up to 48V and 30A main supply current
Scope of delivery
- This Eval Board comes with the already mounted and wired "Reference Motor Board"

Reference Motor Board TEC0060
Reference Motor
The manufaturer of the reference motor is Anaheim Automation and the order no. of the delivered combination of the motor with encoder is BLWR111D-24V-10000-1000SI.
The nominal motor voltage is DC 24V whichi is supplied by DC 12V on the Reference Motor Board. This will cause a certain derating in performace.
The datasheet of the motor:

The datasheet of the encoder:
http://www.anaheimautomation.com/manuals/accessories/L010390%20-%20Single%20Ended%20Encoder%20with%20Index%20Channel.pdf
Internal
Temperature Sensor
Onboard a Maxim 1-Wire Temperature sensor DS18S20Z+ is available, which is located on the potential of the FPGA board as close as possible to the central motor MOSFETs.
Addional 1-Wire temperature sensor can be connected by wire to connector J16:
- Pin 1(DQ), 3 (GND),5 (+3.3V) at the same 1-wire bus as the onboard one
- Pin 2(DQ), 4 (GND),6 (+3.3V) at a separate 1-wire bus
Power and Power-On Sequence
Power Supply
+ DC 12V Motor Driver and Motor Supply
This externaly supplies power sources must be SELV protected (Separated or safety extra-low voltage).
The motor drivers and the reference motor on the pre-mounted motor board TEC0060 are supplied by this voltage.
The internal +5V digital supply is generated out of this +12V supply.
+ DC 5...48V Optional Motor Supply
SAFETY INSTRUCTIONS:
This externaly supplies power sources must be SELV protected (Separated or safety extra-low voltage).
This option is
only usable at your own risk- only allowed to be used for electrical specialist for the used electical voltage and power conditions
- only allowed to be used under electrical laboratory conditions
- only allowed to be used in horizontal position on a non conducting and non-inflammable surface
- only allowed to be used with a wiring, which fullfills the current rating for the maximum possible currents.
- The maximung current might be limited by the used fuse between connector J5 and J6 or e.g. by the limit of an connected external power source.
- only allowed to be used with appropriate connectors at the M5 screw connectors, which means M5 cable lugs must be used and fastend accorting to technical standards.
- only allowed to be used, if the "Eval Boad high current signals" conducting up to 30A nominal, are covered by isolating, mechanically stable material
The "Eval Boad high current signals" are the motor outputs A, B, C and Fuse F1 Connectors J5 an J6 and further internal connections shown white marked in the following picture:
- Highly recommended is to use the delivered "Isolating cover PCB" (marked in green), which needs to be mounted to the mounting holes H1, H9, H3, H4 with the deliverd 10mm isolating spacers:
- The used cable lugs need to be isolated in the area outstanding the outer border of the Eval Board.
Intention is to make sure that the "Isolating Cover PCB" is overlapping the conducting material by a minimum of 2 cm.
Initial operation
The option 2 motor supply is only usable after the following steps are done:
- Disconnecting the reference motor board TEC0060 by unmounting its screws and the encoder cable from J10
- Mounting the deliverd 30A Fuse to the connectors J5 and J6 with the deliverd M5 screws
- For lower supply current requirements, caused by the power rating of the used motor, a fuse with a lower and suitable current rating in the supply wiring is recommended.
- Connecting with a cable lugs the +DC 5..48V to J6 and the corresponding GND to J1.
- The cable length is limited to 3m.
- Connection the three motor phases to J2 (A), J3 (B) and J4 (C).
- The cable length is limited to 3m.
- Optional: connect the encoder wires to J10 or J11
and set jumper field according to signal specification: differential or single ended
