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.

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.

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

The TMdrive-DCe2 is a family of DC system drives for new and

retrofit applications.

Equipped with a 100 GB robust Data Historian, the Power Plant Controller

records high-resolution operational data for granular insight and trend

analysis. Data is structured in three tiers—weekly (1-second resolution),

monthly (30-second resolution), and yearly (10-minute resolution)

—capturing everything from inverter power to skid DC current.

Additional capabilities include remote MSC control via Modbus or DNP3.

and live trending for any transmitted signal, making the controller a vital
