Gen4 PMAC

The Sevcon Gen4 Motor Controller family 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 powerband. 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, forklift trucks and aerial work platforms.
  • Separate operating modes allow for the unit to act as a fully-fledged VCU (Vehicle Control Unit) 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:

• 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 M10 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 so we recommend our Sevcon Gen4 Connector Kit to get started.

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)
