PDF DownloadPress article HEINZMANN (29h January, 2010)
HEINZMANN collaborating with manufacturers of combustion engines to develop innovative hybrid drive concepts. The latest development is being presented at the bauma exhibition in Munich, April 19 – 25, 2010.
Generation 1: distributed winding
- Manual winding design of electric motor
- Housing produced as a one-off customer-specific item
- Length of electric motor: 150 mm/15 kW
Generation 2: single-tooth winding
- Cheap design of electric motor can be automated
- Virtually serial production cast-iron housing with integrated cooling channel
- Length of electric motor: 80 mm / 15 kW
Latest test results for a hybridized construction machine
In a standardised test, a construction machine with a 120 kW diesel engine was compared directly with an identical design of hybridised machine with a hybrid output of 115 kW (55 kW diesel + 60 kW peak output from electric motor) from the equipment manufacturer. The test results show that in actual operation, consumption savings of approx. 20 % can be achieved with the hybrid machine for a simultaneous
increase in productivity of over 40 %. The driving characteristics of the machine, especially acceleration and braking behaviour, were noticeably improved.
The hybrid drive performs the following functions
- Start/stop – avoiding idling phases
- Power boost – covering output peaks with the electric motor
- Recuperation – utilising braking energy to charge the battery
- Charging the battery – using excess output from the combustion engine to charge the battery
- Downsizing/downspeeding – smaller combustion engine, simplifying subsequent treatment of exhaust gas
- On-board power supply – allows electrical consumers (fans, water pump, air-conditioning compressors, 220 V connection etc.) to be supplied with power
- Higher productivity and higher working dynamics
HEINZMANN (www.heinzmann.com)
HEINZMANN was founded in 1897 and is now one of the world’s foremost suppliers of solutions for engine and turbine management. We make mechanical and electronic speed control systems for diesel, gas and dual-engine drives, as well as for turbines.
The product portfolio includes mechanical and hydraulic actuators, analogue and digital control units, electronic injection systems and complete common-rail systems. We also specialize in mixed control systems for gas engines, dual-fuel systems and generator management. Solutions for remote communication and visualization tools complete our range.
The latest new developments are a solution for managing diesel engine emissions and our hybrid drive with an output range up to approx. 100 kW for industrial vehicles with diesel, gas and petrol engines.
Our products are used in marine drives, locomotive control systems, industrial vehicles and combustion engines.
HEINZMANN is also a renowned manufacturer of electric drives up to approx. 60 kW. It develops and manufactures direct-current and brushless disc armature motors, external rotor motors and wheel hub motors for special machines.
Designed for use in rough industrial environments, HEINZMANN drives meet the requirements of an enormous range of applications. The benefits of these high-performance electric motors are their small dimensions, compact design, reliability and ruggedness. They are used in fans and pumps, in handling and robotics, for conveying, moving and positioning and also in light-duty electric vehicles.
