AZG Series

Mahle Electric Drives AZG starters are a range of geared starters designed for high performance requirements for large displacement diesel engines and heavy duty applications. AZG starters are used for commercial vehicles, trucks, tractors, agricultural machinery, construction equipment, mining equipment, ships, generator sets and other applications.

AZG starters are available in 12V (6.5 kW) version — for starting diesel engines with displacement from 6 to 15 liters, and in 24V (9.5 kW) version — for starting diesel engines with capacity from 7 to 19 liters.

A characteristic design feature of the starters of this series is the housing diameter, which for all models of the series is 110 mm. Starters have a planetary reduction gear, increasing the output torque, electric motor part and starting parts. Only the overhang design is used.

Metal low-noise planetary gear with pinion and rubber shock absorber, on the same axis as the armature. 2-stage soft gearing system, preventing damage and overloading of the starter gear and engine ring gear (flywheel) and controlled by a special starting relay. Relay with a retracting and holding winding for effective opening of the main contacts. Brackets on the drive side are made of cast aluminum. High quality heat resistant materials are used.

Advantages of AZG starters:

• design with cantilevered outreach of the gear;
• high specific output power
• high efficiency;
• reliable start of the engine in cold conditions;
• low battery discharge current is allowed.

The parameters of the starter flange and the location of the electrical leads are individually adapted to each specific engine. Oil-tight modifications are available for areas where lubricated couplings are used, ground-isolated versions, additional protection against exceeded starting time, parallel starting system with two or three starters and corresponding electronic unit, which can start diesel engines up to 80l and gasoline engines up to 150 l.

The AZG 4683 is a geared starter, with a rated voltage of 24V, power of 6,5kW, and with a cantilever outreach of the pinion. It is used for the Deutz Agricultural equipment (with BF8L513M, F 8L 513, TCD1215 engines), Kirovets K744 tractors, equipment with Mercedes engines.

The AZG 4686 is a geared starter, with a rated voltage of 12V, 6.5kW, a cantilever outreach of the pinion. It has soft relay and isolated “mass”. Equipped with a new design solenoid relay, which prevents the starter contacts from sticking (FRS system). Used to complete a wide range of agricultural and construction equipment such manufacturers as CHALLENGER, CLAAS, CASE, JOHN DEERE, VERSATILE and others with engines Cummins V Series and Caterpillar 3408, 3412.
