Ac Motor Speed Control 36v 48v 72V 80v current max 400A A5S For AC
Motor controller
Product Description:
A5S series provide advanced control of AC induction motors and
permanent magnet drive motors performing on-vehicle traction drive
or hydraulic pump duties. They offer vehicle developers a highly
cost-effective combination of power, performance and functionality.
The A5S series deployed with multiple patented techniques, that
extend life of build-in relays and MOSFET units, a higher
reliability is achieved.
The motor features vector control technology for magnetic field
orientation and AC motor identification technology, enabling
optimal torque control across the entire speed range.
Typical appication
Small and medium sized utility vehicles, lightweight road vehicles
such as buggies, golf carts, low-speed electric car, pallet trucks
and forklifts, etc.
Features:
Full Featured
- Offers 0~300Hz wide working frequency.
- Available for 400A output at 36-72V system voltages. These are true
2 minute Arms ratings, not short duration 'boost' ratings .
- Support regenerate break, SOC algorithm , magnetic eddy current
brake control, Emergency stop-and-reverse motor control,
Anti-sliding slope.
- Indirect Field Orientation (IFO) Vector Control algorithm generates
the maximum possible torque and efficiency across the entire speed
range.
- Enables quick and easy characterization of the AC motor without
having to remove it from the vehicle, A5 series controllers are
fully compatible with any brand of AC motor.
- Auto temperature compensation, remote calibration.
- Advanced Space Vector Pulse Width Modulation (SVPWM) techniques
produce low motor harmonics, low torque ripple and minimized
heating losses, resulting in high efficiency.
