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.

Note *: 924 uF is capacity of the SL controller without SL capacitor bank. However, the additional capacity is required for ProdTSpecIntro controller operation, thus SL capacitor bank must be always connected. Total capacity with the bank connected is 4444 uF.

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.

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.

Example on how to get heatsink thermal resistance

This example with AX controller shows on how to get required heatsink thermal resistance based on the required phase current amplitude and surrounding temperature.

  1. Define the required phase current (Iphase=50I_{phase} = 50 A for the example)
  2. Get maximum permissible heatsink temperature from the graph "Dependency of heatsink temperature on phase current amplitude" (Ths=57°CT_{hs} = 57°C from the example)
  3. Put the temperature value to the graph "Dependency of heatsink temperature on power losses"
  4. Get required power that needs to be dissipated by the heatsink (P=33P = 33 W from the example)

example

  1. Define the ambient operating temperature (Tamb=25T_{amb} = 25 °C for the example)
  2. Calculate required thermal resistance of the heatsink by using this equation Rhs=ThsTambP=5725330.97R_{hs}=\dfrac{T_{hs} - T_{amb}}{P} =\dfrac{57 - 25}{33} \approx 0.97 °C/W
  3. You can design your heatsink now!

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.
