PRODUCTION DATA
Table 7-27 shows the thermal performance improvements as a result of auto-torque. The thermal images are captured at the following condition:
VM = 24 V, 1/16 microstep, 4A full-scale current, 3000 pps speed, No load, Room temperature ambient
Thermal image: auto-torque disabled, IC temperature = 114.3 °C | Thermal image: auto-torque enabled, IC temperature = 37 °C |
Thermal image: auto-torque disabled, motor temperature = 65.8 °C | Thermal image: auto-torque enabled, motor temperature = 28.1 °C |
Reduction in IC and motor temperature as a result of auto-torque improves long term reliability of the stepper motor system.
