Brushless dc motors

In this paper, the skewing slot is applied to the PM surface mounted Brushless DC Motor 20kW 36 slots and 12 magnet poles (Z = 36, p = 12) for eliminating torque ripples. To observe the skewing stator effect, the stator lamination layers are skewed with different angles. With determined skewing angle, the cogging torque eliminated theoretically and flux density space harmonics are also reduced

In this paper, the skewing slot is considered for the permanent surface mounted brushless DC motor for eliminating torque ripples. In order to observe the skewing stator effect, the stator lamination layers are skewed with different angles. With determined skewing angle, the cogging torque will theoretically reduce and the harmonic components of the flux density space are reduced, as well.

It is important to have speed control of motors on UAVs since the system dynamics are related to the rotation speed of the motors. This paper presents a sensorless phase voltage detection scheme to measure the rotation speed. A PID controller is implemented to ensure the performance of the motors. A mathematical model of Delta-Connected BLDC motors is built for analyzing the relationship between phase voltage and rotation speed.

A drive sizing makes sure that the drive has enough torque to satisfy the load requirements to overcome friction losses, provide sufficient load thrust, and provide enough acceleration torque for the type of acceleration required. Once the drive-sizing requirement is satisfied, the servo drive stability must be addressed. Stabilizing the servo drive is a matter of adjusting the servo compensation. All industrial servo drives require some form of compensation often referred to as proportional, integral, and differential (PID).

1. STEPPER MOTOR SYSTEMS OVERVIEW Motion Control, in electronic terms, means to accurately control the movement of an object based on either speed, distance, load, inertia or a combination of all these factors. There are numerous types of motion control systems, including; Stepper Motor, Linear Step Motor, DC Brush, Brushless, Servo, Brushless Servo and more. This document will concentrate on Step Motor technology. In Theory, a Stepper motor is a marvel in simplicity. It has no brushes, or contacts.

Brushless DC (BLDC) motors are synchronous motors with permanent magnets on the rotor and armature windings on the stator. Hence, from a construction point of view, they are the inside-out version of DC motors, which have permanent magnets or field windings on the stator and armature windings on the rotor. A typical BLDC motor with 12 stator slots and four poles on the rotor is shown in Fig. 10.1. The most obvious advantage of the
