Physics VCE Units 3 & 4 Practice Question 5 – Motor torque factors

Q5 Physics Motor torque factors Unit 3 - AOS 2

Question 5

6 marks

An engineering team is designing a high-torque DC motor for a robotic arm used in an automated manufacturing process. The motor needs to provide precise and consistent torque under varying load conditions. The team is considering two different design options:

  • Option A: A motor with a relatively low current rating but a large number of wire loops in the coil.
  • Option B: A motor with a higher current rating but fewer wire loops in the coil.

Discuss the advantages and disadvantages of each design option with respect to achieving high and consistent torque output. Consider the factors that influence torque in a DC motor and how each option addresses the requirements of the robotic arm application. Justify which option you would recommend.

Unit 3 Overview

In this unit students use Newton’s laws to investigate motion in one and two dimensions. They explore the concept of the field as a model used by physicists to explain observations of motion of objects not in apparent contact. Students compare and contrast three fundamental fields – gravitational, magnetic and electric – and how they relate to one another. They consider the importance of the field to the motion of particles within the field. Students examine the production of electricity and its delivery to homes. They explore fields in relation to the transmission of electricity over large distances and in the design and operation of particle accelerators. A student-designed practical investigation involving the generation of primary data and including one continuous, independent variable related to fields, motion or light is undertaken either in Unit 3 or Unit 4, or across both Units 3 and 4, and is assessed in Unit 4, Outcome 2. The design, analysis and findings of the investigation are presented in a scientific poster format.

How do things move without contact?

In this area of study, students examine the similarities and differences between three fields: gravitational, electric and magnetic. Students explore how positions in fields determine the potential energy of, and the force on, an object. They investigate how concepts related to field models can be applied to construct motors, maintain satellite orbits and to accelerate particles including in a synchrotron.

Key Knowledge Detail

Investigate, qualitatively, the effect of current, external magnetic field and the number of loops of wire on the torque of a simple motor.
