Sakor develops dynamometer system for major off-highway supplier


Sakor Technologies has announced it has developed a powertrain dynamometer system for a major off-highway drivetrain components supplier.

The highly configurable new test stand is capable of adapting to any torque transfer device geometry and suitable for testing clutches and transfer cases.

One of six built for the customer, the system features dual 420 kW dynamometers that can operate at up to 6,000 revolutions per minute (rpm) and offers maximum continuous torque of 4,010 Nm/s, with up to 150% overload for up to 30 seconds.

The system is controlled by the Dynamometer manufacturer’s DynoLab data acquisition and control system, which provides reliable fully automated test procedures for all customer testing protocols.

Featuring unique adjustable output geometry, which enables users to configure the system to account for different input and output shaft center lines and drop angles, testing is less expensive and safer, providing better data accuracy. It also reduces system set up time. A modular cooling system is mounted below the dynamometer and can be easily accessed for maintenance.

Featuring a wide array of data acquisition channels, the new test stand can collect information on temperature, pressure, flow, and speed. With controller area network (CAN) ports for communication with the customer’s smart controllers, the system can automatically shift the unit under test and also has the ability to directly control older devices that lack CAN communication capability.

“The new test stand has been built for maximum flexibility and adjusts quickly and easily to any transfer case system being tested,” said Randal Beattie, president of Sakor. “It takes minimal operator time to set up and install test units, so what used to take many hours and long drive shafts can now be done in a matter of minutes.”
