TMdrive®-10e2 DP
The TMdrive-10e2 Dual Purpose Drive enables a smooth transition from DC to AC motor systems, offering unmatched flexibility, simplified upgrades, and improved efficiency for modernization projects.
Seamless Transition from DC to AC Motor Systems
The TMdrive-10e2 Dual Purpose (DP) Drive is engineered to support modernization efforts by allowing users to control either DC or AC motors using a single hardware platform. By simply switching the firmware between DC and AC configurations, operators can phase upgrades to meet operational schedules and budget constraints. Initially configured for DC motor control, the same TMdrive-10e2 DP unit can later power and control a new AC motor without replacing the drive. This flexibility minimizes downtime, maximizes investment, and supports long-term system scalability.
Improved Efficiency and Power Performance
The Dual Purpose drive utilizes standard TMdrive-10e2 hardware and offers significantly improved performance over traditional thyristor systems. Its IGBT gating reduces armature RMS current ripple by over 3:1, resulting in lower motor heating and better commutation. While DC motor applications require additional auxiliary filtering panels, upgrading to AC restores the drive’s full power capacity—enabling significant output increases. With a regenerative converter operating at unity power factor (1.0 PF), the TMdrive-10e2 DP reduces infrastructure demands and energy costs, making it an ideal choice for facilities seeking long-term performance and reliability.
Features and Benefits
- Standard TMdrive-10e2 uses IGBT gating with Pulse Width Modulation
- Four quadrant regenerative operation from DC armature
- Non-reversing, non-plugging field power
- Standard TMdrive-10e2 converter DC source used for all AC and DC drives
- Converter operates with reduced harmonics and unity power factor for reduced impact on the plant power system
