General specification

Parametervalue
Switching frequency20 kHz
Maximum motor magnetic field speed2 kHz
Minimum motor phase inductance2.5 μH
note

Minimum motor inductance is inductance of one winding (half of inductance between motor terminals). Motor inductance usually drops with increasing current due to saturation of motor magnetic circuit. This effect must be also considered when evaluating motor minimum inductance.

warning

If motor inductance is lower than specified, controller lifetime could be significantly reduced (even orders of magnitude). Low inductance increases electrolytic capacitors ripple current thus their temperature and lifetime.

Terms explanation:

  • The controller delivers maximal current without limitation if the battery voltage is below the Maximum working voltage and above the Minimum working voltage.
  • The output current is proportionally limited if the battery voltage is above the Maximum working voltage and below the Full limitation voltage. This is indicated by the "Overvoltage" status.
  • The output current is fully limited if the battery voltage is above the Full limitation voltage and below the Critical error voltage (max). This state is indicated by the "Overvoltage" status. The controller automatically recovers if the voltage falls below the Full limitation voltage.
  • The controller falls into critical error if the battery voltage exceeds the Critical error voltage (max). The controller can be permanently damaged in this region and does not recover automatically, it needs to be turned OFF and ON again.
  • The output current is proportionally limited if the battery voltage is below the Minimum working voltage and above the Threshold voltage. This is indicated by the "Undervoltage" status.
  • The output current is fully limited if the battery voltage is below the Threshold voltage and above the Critical error voltage (min). This state is indicated by the "Undervoltage" status. The controller automatically recovers if the voltage rises above the Threshold voltage.
  • The controller falls into critical error if the battery voltage falls below the Critical error voltage (min). The controller does not recover automatically, it needs to be turned OFF and ON again.

1/ Irrespective of the actual temperature conditions, the immediate output current will be clamped to these values by the I2R limiter in the order of seconds. When motor is rotating, power losses are divided between all three phases and the controller is able to supply higher per-phase current amplitude. When the device is super-cooled from outside, this is the maximum theoretical continuous RMS current.

2/ This current can be delivered in short bursts and reflects the current measurement range of every variant. The sufficient margin for current ripple of the switching waveform must be accomodated within the range. Any higher current triggers DTC / active short circuit protection.

note

Listed power (peak and nominal) is output power from the controller (input power to the motor). Output power from the motor (mechanical power) depends on the efficiency of the motor and controller settings.

Output protection and current limiting

Inputs and outputs are protected against shorting in the following manner:

  • Each phase is protected against shorting to another phase
  • Phase A and C are protected against shorting to BATT+ and BATT-
  • Signal pins with voltage lower than 5 V are protected against shorting to each other

Advanced protections such as maximal power protection, undervoltage, overvoltage, thermal protection, and cycle-by-cycle current limiting are also implemented.

Thermal specification

Maximum power losses

Controller maximum temperature is internally limited to approximately 100°C. The maximum output current (or maximum power losses) for this limiting temperature is given by the temperature of the heatsink. Dependencies are given in the following graphs.

Thermal graphs for AM controller are not yet available. Please refer to the power dissipation calculator below.

Power losses calculator

Controller power losses are affected by the two main factors: motor phase current and DC link voltage. The following calculator can be used for rough estimate (~10% accuracy) of power losses in the controller. Calculation is valid for VECTOR driver.

Power losses:

Mounting and cooling tips

  • Place controller in a well ventilated area. Use a sealed, waterproof housing and put it outside the vehicle rather than inside. Contact with moving air improves cooling.
  • If possible, fasten the controller to large metal parts, such as a frame. This works as a heatsink and helps conduct heat away.
  • If using an external heatsink or fastening the controller to metal parts, make sure both surfaces are flat, clean, and fit to each other. Apply a suitable amount of thermal grease to both surfaces.
  • Use a thin layer of thermal grease rather than too much.

note
  • Long device operation at high temperatures reduces the device lifespan.
  • Sealed rating requires sealed enclosure and cables secured against any movement.
  • Non-sealed rating applies when enclosure is non-sealed or cables are not secured.
  • All connectors must be properly mated for the stated ingress protection.

EMC specifications and guidelines

The controller performs rapid switching of high currents, which can generate electromagnetic interference. EMC performance depends on the whole product, not only on the controller. To improve EMC performance:

  • Use power wires with appropriate cross-section. Higher cross-section means lower resistance, lower voltage drops, and lower thermal losses.
  • Use short wires when possible.
  • Use shielded cables. Connect shielding to appropriate ground on one side only to prevent ground loops.
  • Use twisted pairs. Differential signal wires (e.g. CAN Low and CAN High) should be twisted together.
  • Twist power wires. Twist BATT+ with BATT- and twist motor phases A, B, and C together.
  • Place signal wires separately from power wires. When crossing, signal wires should be perpendicular to power wires.
  • If possible, connect motor chassis to BATT- close to the controller. If not possible, use a Y capacitor between them.
  • Use galvanic isolation to prevent ground loops.
  • Use signals with appropriate grounds. Do not mix signal grounds and power grounds.
