Traction Drives

MITRAC, Muscles

The Muscles of the Train

The MITRAC portfolio embraces a full range of dual- and single-axle bogie drives for low-, medium- and high-power applications designed to meet the needs of any railway operator.  When we approach a new assignment, we draw on the years of experience gathered from supplying railroad operators in every corner of the globe with all types of equipment. We aim to develop optimum solutions that exceed the expectations of both our customers and the industry. An optimized design according to the fundamental requirements of available space, axle load and speed result in a highly reliable energy efficient solution with low maintenance effort during the whole lifetime of the product.

At Bombardier, we have perfected the modular system architectures that enable us to develop customized solutions for any application. This unique combination of high modularity, efficiency, reliability and ease of service and maintenance means low life-cycle costs with a dependable revenue source. With a leading-edge design, modern simulation tools and intensive product testing, these systems ensure streamlined performance and reliable operation at all times, in any situation.

Nose-suspended drives

This robust, uncomplicated design is geared to minimize the service and maintenance needs, generates high tractive output at low speeds, and is ideal for general and heavy-haul freight service.

Partly suspended drives

This design has a low unsprung mass, which enables high speeds with low track wear. The single reduction gear unit requires a lower upfront investment than any other drives system.

Fully suspended drives

This sophisticated concept features the lowest unsprung mass and facilitates high speeds and performance combined with low track wear.

Permanent Magnet Motor

The compact MITRAC Permanent Magnet (PM) Motor system is specifically designed to meet the highest demands on drive systems for traction applications while achieving higher power efficiency than conventional motors: Maximum torque over a wide speed range where the motor is especially competitive at high speed and low voltage, environment variations and stress as well as safety requirements. This has been achieved with a minimum of hardware and software changes to other parts of the propulsion system, and design re-use of the well proven and highly reliable conventional MITRAC motors.

Traction drives for light rail vehicles, people movers and trolley buses

Bombardier Transportation has taken up the "system vehicle" challenge. For years, the trend in the tram sector has been towards modular vehicle systems. To satisfy the requirements for affordable drives and superior design adapted to modern vehicle concepts, Bombardier has developed a series of successful configurations.

Pace-setting Drives

This success is based on Bombardier’s ambitious requirements on the reliability, safety, energy efficiency and low life cycle costs in the entire product range. The drives optimally exploit the converters’ characteristics and are designed to fit within a bogie’s limited space.

Drives for every Low Power Application

The MITRAC DR 500 family offers the right drive solution for every tram, streetcar or automated people mover application. The selection of the right configuration of traction motor and its associated gear is essential for a powerful, high performing and reliable drive.

An optimized design according to the fundamental requirements of available space, axle load and speed results in a highly reliable solution with low maintenance effort during the whole lifetime of the product.

Traction drives for metro, regional, intercity and high speed trains

Traction drives for metro, regional, intercity and high speed trains

Steady urbanization and growing population densities in towns are increasing the need for modern urban mass transport facilities as well as for regional and intercity transport systems. In terms of traction drives Bombardier effectively caters for this wide range of applications with its standard MITRAC Drive 1000 traction drive range.

Pace-setting Drives

This success is based on Bombardier’s exacting requirements on the reliability, safety, energy efficiency and low life cycle costs in the entire product range. The drives optimally exploit the converters’ characteristics and are designed to fit within a bogie’s limited space. Bombardier has also launched a robust series of permanent magnet motors optimized for rail applications.

Drives for every Medium Power Application

The MITRAC Drive 1000 family offers the right drive solution for every high speed-, intercity-, regional- and commuter train as well as for metro applications. The selection of the right configuration of traction motor and gear is essential for a powerful, high performing and reliable drive. An optimized design according to the fundamental requirements of available space, axle load and speed result in a highly reliable solution with low maintenance effort during the whole lifetime of the product.

Traction drives for locomotives and powerheads

Drives of the MITRAC DR 3000 family are designed to satisfy the requirements of all types of locomotives and power heads. Partly or fully suspended drive concepts for highest speeds as well as nose-suspended drive variants for freight transport are to be found in the MITRAC DR 3000 drives family.

The forced air-ventilated MITRAC TM 3000 asynchronous traction motors are highly standardized and provide exceptional reliability. Some 12,000 traction motors out of the MITRACTM 3000 portfolio are on the rails worldwide.

Pace-setting Drives

This success is based on Bombardier’s exacting requirements on the reliability, safety, energy efficiency and low life cycle costs in the entire product range. The drives optimally exploit the converters’ characteristics and are designed to fit within a bogie’s limited space.

Drives for every High Power Application

The MITRAC DR 3000 family offers the right drive solution for every high power freight or passenger train. The selection of appropriate suspension type depends on the required vehicle speed and tractive effort: Partly suspended drives are best for power heads for high speed trains with low tractive effort.

PPC Drives 3400

On the other end of the spectrum, Bombardier offers robust and maintenance friendly nose-suspended drives are and fit best for freight locomotives requiring high traction effort at moderate speeds. For universal and passenger locomotives that require higher speeds and/or minimal wear of the tracks,  Bombarider offers fully suspended drives, which have the lowest unsprung mass.
