Electrical and power specifications
Part number
→
EAR-3/40-C-P
Power supply nominal voltage
8 V
DC
to 40 V
DC
Transient peak voltage
44 V (1 s) 48 V (10 ms)
The drive includes a high power TVS (transient Voltage
Suppressor) that can absorb small overvoltage peaks and
clamps at 50 V.
Logic supply voltage
Not needed, supplied from the power supply voltage.
5 V supply output
5 V ± 3% 350 mA max. output for feedbacks or other purposes.
Internal DC bus capacitance
23 µF
Minimum motor inductance
100 µH
Nominal phase continuous current
3 A
RMS
(50 ºC air temperature, no heatsink needed)
Maximum phase peak current
6 A
RMS
(5 s)
Current sense range
± 8.25 Apk (full range)
Accuracy is better than ± 2% between -6.5 A and 6.5A. Current
sense error can be up to ±10% outside this range.
Current sense resolution
16.11 mA/count (10 ADC bits)
Cooling
Natural convection or by gap pad touching power stage
transistors in case current is needed at high temperature or no
air convection is available.
Note that soldering the drive to a daughter board with big GND
plane will improve heat dissipation through the pins.
Connectors
2 pin headers 2.54 mm pitch on 2.54 mm matrix. MicroUSB
connector.
Standby power consumption
0.5 W @ 8 V supply, 0.6 W @ 24 V, 0.9 W @ 36 V, 1 W @ 40 V
(max. without feedbacks or 5 V connected)
Efficiency
> 95% power stage efficiency at the rated power and current
