rotabench® EPS/CT is a precision instrument for measure the cogging torque of an electric motors. It was developled originally to measure the cogging torque of electric motors for Electric Power Steering (“EPS”) applications, but is applicable for any other motor type.
The mayor components are:
- mechanic setup made from milled aluminium parts
- Maxon EC drive
- Hollow-shaft encoder with 2048 Tics per revolution
- and a Lorenz DR2512 torque sensor
Specification
- Speed: max. 120 rpm (typ. – depending on customer requirements)
- max. Torque: 0.2 Nm, 0.3 Nm, 0.5 Nm or 1.0 Nm torque sensor
- weight: approx. 40 kg
- Drive: maxon EC drive with ceramic gearbox
- flange diameter: 169.9mm
- Encoder: 2048 Tics per revolution
- Sample-Rate: max. 5 kHz (theoretically, at 120 rpm and max. resolution)
Software
The test bench is operated from a Windows PC, which is connected to the device through Ethernet:
