The Sevcon Gen4 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 Size 10 unit is liquid-cooled and offers one of the most compact solutions for a motor controller of its powerband. The 700V Gen4 Size10 variant can provide a peak current output of 400A. The unit supports regenerative braking to reduce power consumption. A fully isolated logic and IO circuit allows for total separation of the high and low power system buses to improve safety and reliability. High voltage power connections are sealed with a protective cover and cable glands to maximize IP protection and touch safety. Equipped with a secondary supervisory safety processor, product options are available for ISO26262 ASIL C compliance.

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, forklift 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.

Communication:

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 range provides support for the following motor types and control modes:

• PMAC
• Induction machine (Open-loop Slip Control)
• Induction machine (Flux Vector Control)

Encoder Support:

The Gen4 range provides support for the following sensor types:

• A
• AB
• UVW
• ABUVW
• Sin/Cos (Specific hardware only)
• Resolver (Size 8 and 10 models only)

Connectivity:

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 35-Way Ampseal connector. Signal connections include:

• 1x Encoder connection (power supply and signal connections)
• 2x CAN bus connection (internally linked. Termination available)
• 8x Configurable digital inputs
• 4x Configurable analogue inputs
• 3x Configurable contactor driver outputs
• 1x Thermistor input
• 5V and 10V power supply outputs (Specific hardware only)
