Torque controller for brushless DC motors

IEEE Transactions on Industrial Electronics, 1999
A high-performance torque controller is proposed for three-phase brushless DC motor drives. The strategy is based on variable-structure control and a new synchronous reference frame is utilized. Advantages over conventional strategies include improved dynamic performance, reduced acoustic noise, improved drive efficiency and enhanced inverter ...

A computer-controlled torque motor

Measurement Science and Technology, 1990
The authors describe an inexpensive intelligent controller for laboratory torque motors, or any other analogue positioning device. The instrument is based on a single-board microcomputer, and is programmed in the high-level language FORTH. It may be interfaced to a general purpose computer via one of two serial ports, and may also function as a stand ...

Speed-Torque Characteristics of Torque Motor with Tape Winding Stator

Известия высших учебных заведений. Электромеханика, 2021
The speed-torque characteristics of a torque motor with a new type of active element – the tape winding is considered. The analytical studies of the motor speed-torque characteristics determination is difficult because it is required to take into account the distributed current flowing through the winding elements.

Auto-compensation of torque ripple of DD motor by torque observer

Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting, 2002
A torque control system for DDM (direct drive motor) with a permanent magnet rotor equipped with a torque observer implemented by software of a digital signal processor is proposed. The speed fluctuation against a disturbance can be fully removed with a torque feedforward loop.

Robust torque optimization for BLDC spindle motors

IEEE Transactions on Industrial Electronics, 2001
A robust design for torque optimization of brushless DC spindle motors applied in a hard disk drive, using the Taguchi method, is described and illustrated in this paper. The optimal design process takes into consideration noises that arise in the manufacturing process, such as manufacturing tolerances for the stator tooth shape and variation of the ...

Induction Motors Torque Control

2001
In this chapter we shall study some modern algorithms and techniques used for controlling induction motors. Study of the control of three-phase induction motors has been our objective throughout this book. However, this aim would be difficult without a comprehensive analysis of the operation of such devices in both steady states and transient regimes ...
