TMdrive-10e2 SPR
The TMdrive-10e2 SPR Slip Power Recovery Drive System for Wound Rotor Motors belongs to the TMdrive-10e2 family of low-voltage system drives designed to lower the cost of ownership with numerous space-saving and maintenance features.
When wound rotor motors are employed, the TMdrive-10e2 Slip Power Recovery Drive (SPR) can help make operations more efficient. The drive operates at high power factor with low harmonics. When operating below base speed, the drive returns power to the line, saving on power consumption. The TMEIC SPR drive also allows operation above synchronous speed enabling increased throughput, within the mechanical limits of the system. It is also ideal for retrofits of existing, previous-generation current source SPR drives.
With the TMdrive-10e2 SPR, wound rotor motors have entered the 21st Century offering:
PWM converters
High power factor operation
High reliability
Low cost of ownership
TMdrive-10e2 SPR Features and Benefits
Design Feature
Based on Standard Drive – Standard TMEIC low voltage drive hardware is applied for use as a wound rotor motor drive
High Power Factor, Low Harmonic Utility Interface – Source converter feeding power back into utility operates at unity power factor.
Low Harmonic Currents in Rotor Circuit – PWM converter connected to rotor provides sinusoidal current to rotor
Latest Drive Control Technology – Based on current production drive control hardware and firmware.
Heat Pipe Cooling Technology – The cabinet-based IGBT power bridges use heat pipe cooling technology.
Precise control of wound rotor motor while not wasting energy
Customer Benefit
Reliable Drive Hardware & Available Spare Parts – modifications to the TMdrive-10 drive hardware are required for use as a slip power recovery drive
Reduction of Current to Motor and Reduced Harmonics – Higher PF operation means reduced reactive power demands and better voltage stability Reduced harmonics result in no filtering on utility supply
Negligible Rotor Heating and Smooth Motor Torque – Sinusoidal current in rotor circuit results in negligible rotor heating and torque pulsations
Intelligent Drive Control – Using modern drive control provides the latest in drive communications, operating accuracy, and diagnostics
Reduces Footprint and Lowers Audible Noise – This cooling system reduces the space required for effective IGBT cooling. It also lowers the speed of the cooling air, thereby reducing audible noise
Drive controls motor torque (rotor current) directly; motor does not have to increase slip (slow down) to increase torque
Slip power is recovered and fed back to power system when the motor is operating below synchronous speed
TMdrive®-10e2 DP
Dual Purpose Drive
The TM10e2 Dual Purpose (DP) Drive is the ideal solution for modernization projects where the user wishes to upgrade from a legacy DC system to a modern AC system. The TMdrive-10e2 Dual Purpose drive is capable of controlling either a DC or AC motor. This capability allows for flexibility in planning system modernizations in a manner that accommodates constraints created by operating demands and budgetary considerations. New AC motors can be powered and controlled using TM10e2 DP drives with AC motor control firmware installed. DC motors can be powered and controlled using TM10e2 DP drives with DC motor control firmware installed. DC Motors can be replaced at any time with AC motors and powered by the previously installed TM10e2 DP drives.
The Dual Purpose drive uses standard TMdrive-10e2 drive power and control hardware for both AC and DC motor control. When DC motors are upgraded to AC, the drive can be reconfigured for AC motor control by switching the firmware from the DC to the AC motor control function set. The drive can then be quickly re-tuned to achieve the required operational performance.
Requirements
DC and AC motors have different physical and electrical requirements. In addition to the standard TMdrive-10e2 AC drive, an auxiliary panel with both armature and field circuit filters is required for the DC motor, shown in the figure below.

TMdrive-10e2 DP Drive Ratings
When applying the TMdrive-10e2 Dual Purpose Drive as DC motor control, the AC KW capability is de-rated. The extra capacity becomes available again when the DC machine is upgraded to AC, allowing for a potential power increase based on process requirements. For the example shown here, the Frame 100 applied as a DC drive produces 32.3 KW. Applied as an AC drive the Frame 100 can produce up to 82.4 KW.

Comparison between Thyristor and IGBT Systems
The TMdrive-10e2-DP IGBT gating reduces armature RMS current ripple more than 3:1 compared to traditional 6-pulse thyristor drives. Reduced RMS ripple results in lower motor heating and better commutation. Legacy DC drive systems operate at a Power Factor (PF) between approximately 0 and 0.8 lagging with appropriately sized infrastructure. The TMdrive-P10e2 regenerative converter operates at 1.0 PF with smaller cables and transformer requirements, higher efficiency and lower utility costs. If the existing utility infrastructure is marginal, it will be more robust after upgrading with the Dual Purpose Drive system.
