BorgWarner develops new commercial vehicle starter

BorgWarner has expanded its portfolio with the introduction of a new commercial vehicle starter. Through key design improvements, the 31MT starter offers increased reliability, durability and up to 10% more peak power.

“BorgWarner’s new 31MT commercial vehicle delivery starter is expected to expand our product portfolio for medium-duty vehicles and fills the need for a durable, reliable starter for class 6 and 7 commercial vehicles,” said Dr Stefan Demmerle, president and general manager, BorgWarner PowerDrive Systems.

“It is an ideal solution for applications that make a lot of starts and stops or operate under stressful driving conditions.”

During development, BorgWarner engineers made a series of design changes to improve the performance of the heavy-duty starter. These changes include a new silicon lamination armature for increased cranking power; enhanced commutator and a new bearing with O-ring for greater starter durability; and stainless brush springs and a new plated brush holder for added corrosion resistance and overall performance.

An innovative feature of the 31MT is its positive shift engagement system, which is activated in case of tooth abutment. If this occurs, the armature rotation in full power clears the abutment to allow pinion engagement.
