• Gen4 DC 72V 550A

The Sevcon Gen4 DC Motor controller combines over 50 years of expertise into a robust, reliable and proven motor controller which is highly configurable to a number of application functions. The unit is air cooled and offers one of the most compact solutions for a motor controller of its power band. The 72V Gen4 DC variant can provide a peak current output of 550A. The unit supports regenerative braking to reduce power consumption. 

Recommended Applications:

The Gen4 range of motor controllers can be used across a wide range of applications, for example:

  • Ideal for traction applications such as mopeds and go-carts, motorbikes, city cars, fork lift trucks and aerial work platforms.
  • Separate operating modes allow for the unit to act as a fully fledged VCU master or as a simple torque slave unit.
  • Sevcon Pump Application technology allows the unit to drive a pump motor.
  • Specialist support for safety-critical power steer applications.


The Sevcon Gen4 range supports configuration, calibration, control and status monitoring over a CAN bus using the industry standard CANopen protocol. In order to support a wide range of applications, the unit is able to be configured as either an NMT master or slave device.

Gen4 controllers can be configured to support limited compatibility with a J1939 bus.

To take full advantage of the features of CAN communication on a Sevcon product, an IXXAT CAN to USB device with Sevcon DVT Software subscription will be required.

Ingress Protection:

The Sevcon Gen4 range is IP66 rated, providing total protection against dust ingress and protection against water ingress during high powered pressure washing.

Motor Support:

The Gen4 DC range provides 4 Quadrant armature control support for DC SEM motors

Encoder Support:

The Gen4 DC range provides support for the following sensor types:

  • Sensor-less
  • A
  • AB
  • UVW
  • Sin/Cos


Power connections are made through M8 terminal posts. This includes the DC link from a battery or other source via a fuse (mounted on-board) and 3-phase output to the motor.

Signal connections are made through a 23-Way Ampseal connector. Signal connections include:

  • 1x Encoder connection (power supply and signal connections)
  • 1x CAN bus connection (Termination available)
  • 3x Configurable digital inputs
  • 2x Configurable analogue inputs
  • 4x Configurable contactor driver outputs
  • 1x Thermistor input
  • 5V and 10V power supply outputs rated for 200mA each
