#High speed mode sevcon millipak at zero full
125HZ offers the most accurate and fast response in ultra-low RPM’s as well in full speed.ĬAN bus operation happens in the CAN-Open protocol which is linked with the UNI-protocol, this adds the possibility of customizing the CAN-Open EDS inside the PUMP controller. actual model installed in the Twizy is a Sevcon Gen4 controller. Speed measurements with a dynamic polling rate of approx. SEVCON programming dongle for Millipak controllers second hand Sevcon Gen4 controllers are designed to control 3-phase AC induction motors and Permanent Magnet AC ( PMAC) motors in battery powered traction and pump applications. By combining these measurements, the HSE-Pump controller can be configurated so that if torque demand increases (for example by asking for more oil) speed will increase and with less or no torque speed will be low, therefor in a pump application you will have a quitter and more efficient systems delivering only power and hydraulic flow if ask for by torque.Īnother configuration could be if speed compensation is required, so if demanding 30% speed it will deliver 30% speed independently from the load.Ī perfect balance between power and efficiency are provided by the dynamic PWM control frequency that automatically adjust frequency and PWM resolution to obtain the silicon’s maximum. It can deliver high torque at low speed, thanks to its boost stage and speed measurement. The HSE- Pump controller offers high power at small size.
