BAC 500-48-35
PRODUCT DESCRIPTION
FEATURES
The ASi BAC Ne 500 is a high power density electric bike controller
that utilizes the latest in sinusoidal field oriented control to ensure
smooth and quiet brushless DC motor operation and efficient vehicle
operation. Eliminating the traditional metal case, the profile is
minimized by encapsulating the controller in a durable polymer. The
BAC Ne 500 is available in 2 models:
•
•


BAC Ne 500-48-35
BAC Ne 500-48-50
The BAC Ne 500 can operate over a nominal voltage range of
24VDC to 48 VDC. A robust MOSFET-based three phase bridge
provides peak efficiencies in excess of 95%, no audible noise and can
switch motor currents up to 70A peak. In addition to Hall sensor
based motor commutation, sensorless commutation is also
supported.
0 to 10 Volt analogue state of charge protocol is supported.
Alternatively, a software based voltage model of the battery can be
used to derive battery state of charge. Communication to the drive is
via a proprietary ASi object dictionary using the ModBus RTU
protocol.
Standard product at the physical layer includes TTL 232 and RS 485
protocols, which can be substituted with optional LIN & CAN OPEN
configurations.
Programmable performance mapping allows throttle, torque, pedal
and wheel speed sensor inputs to be adjusted via the ASi BACDoor™
PC configuration software to meet specific performance
requirements.
