Specifications of TMdrive-30 and TMdrive-P30

Features

(1) High performance and high reliability

Use of a large capacity IGBT improves the reliability, reduces the switching loss, and improves the control

performance. The control circuit uses a newly developed power electronics equipment control processor

PP7 and an eight-layered surface mounting circuit board, ensuring high component integration and high

reliability.

(2) Highly precise speed control (TMdrive-30)

Use of totally digital and vector control ensures highly precise speed control and high speed response.

(ωc = 60 rad/s, ωc = 20 rad/s for speed sensor-less control)

(3) Transient response and stability

Use of totally digital and vector control makes it possible to ensure stable operation characteristics

including the transient status.

(4) Quadrantal operation (TMdrive-30)

Quadrantal operation, normal, reverse, power running, and regenerative operations are made smoothly.

(Note: This feature applies only when the reverse-parallel thyristor converter (TMdrive-T30) or IGBT

converter (TMdrive-P30) is used.)

(5) Supporting various speed sensors (TMdrive-30)

Drives a squirrel-cage induction motor. A pulse generator or high-resolution brushless resolver can be

used as a speed detector installed in the motor. Speed sensor-less vector control is also possible.
