SpeedStart

The SpeedStart Belt Integrated Starter Generator from CPT is designed to substitute the standard alternator in P0 belt-driven motor generator hybrid applications. It can also substitute the starter motor depending on the application.

SpeedStart is compatible with 12V, 14V and 48V electrical architectures. Each of these can deliver efficient electrical generation and can recuperate the kinetic energy normally lost during vehicle deceleration. With good efficiency over a varied speed range, fuel consumption and emissions are reduced because the electrical energy is returned to the crankshaft.

Our Switched Reluctance (SR) motor technology uses advanced thermodynamic design to harvest higher levels of recuperated energy over extended periods of time. This harvest is also much more frequent compared to other e-motor technologies.

State-of-the-art components were used to develop the control and power electronics for SpeedStart. This in-house process allows us to customise components to meet specific performance requirements. Liquid cooling is used for thermal management, maximising functionality up to 105°C and progressively de-rating performance to 120°C.

At CPT we use industry standard electro-magnetic simulation tools to optimise winding topographies for specific application requirements. These tools also allow us to specify machine features for efficiency and manufacturing purposes.

Our software and motor control strategies were also developed in-house, based on a combination of simulation capabilities and industry standard tools to determine the machine operation mode. This enabled us to control torque, current, speed and voltage. Our development methodologies are A-Spice compliant and ISO 26262 compliance is also available subject to customer requirements.

CPT is an innovative company specialising in the development of driveline electrification solutions for harmful emission reductions and fuel efficiency improvement. Our SpeedStart Belt Integrated Starter Generator has a range of benefits for the mechatronics industry, including thermal management, controllability, functional safety, low parasitic losses, CO2 reduction and advanced emission reduction.
