High torque meets high speeds
High-speed spindle applications demand exceptional performance at elevated rotational speeds. Continuous high-speed operation causes motor heating with conventional servo drives.
Critical requirements include consistent torque delivery at all speeds, protection of motor windings and bearings, minimal thermal stress on components, and position control capability for positionable spindles.
High PWM frequency and filters for more efficient spindles
Triamec servo drives offer selectable PWM frequencies of 50 kHz or 100 kHz. 50 kHz suits most motor types and applications. Switching to 100 kHz PWM provides additional benefits for low-inductance spindle motors, reducing power losses and thermal stress to extend motor and bearing lifetime.
The 100 kHz control loop delivers precise positioning performance across all power ratings, enabling shorter processing times in high-speed spindle applications. Motor-side filters suppress common-mode voltages to protect bearings and windings. T-series filters combine sinus and common-mode filtering for low-inductance motors, while C-series filters provide common-mode protection for all motor types.
