Nidec

Nidec is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nidec rather than just read about it. In short: Nidec Corporation (ニデック株式会社, Nidekku Kabushiki gaisha), formerly known as Nippon Densan Corporation (日本電産株式会社, Nihon Densan Kabushiki gaisha), is a Japanese manufacturer and distributor of electric motors. Their products are found in hard-disk drives, electric appliances, automobiles and commercial and manufacturing equipment.

Key takeaways

Nidec belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nidec to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nidec from memory before moving on to harder problems.

Reference excerpt

Nidec Corporation (ニデック株式会社, Nidekku Kabushiki gaisha), formerly known as Nippon Densan Corporation (日本電産株式会社, Nihon Densan Kabushiki gaisha), is a Japanese manufacturer and distributor of electric motors. Their products are found in hard-disk drives, electric appliances, automobiles and commercial and manufacturing equipment. The company is the global market leader for the spindle motors that power hard-disk drives. The two largest product groups are hard-disk drive motors and automotive products with 16% and 22% of sales, respectively. As of 2017, the company has 296 subsidiaries companies located across Japan, Asia, Europe and the Americas. Nidec is listed on the first section of the Tokyo Stock Exchange and is a constituent of the TOPIX 100 stock market index. The company was number 42 on the 2005 edition of the Businessweek Infotech 100 list. Also Nidec was featured on the 2014 Forbes World's Most Innovative Companies list.

History

Nidec acquisitions Nidec ASI. In 2012 Nidec acquired Ansaldo Sistemi Industriali S.p.A. which became Nidec ASI. Since 2012 Nidec ASI has been involved in comprehensive drive technology. As a part of the Nidec Group, the core business of Nidec ASI S.p.A. includes energy, marine, metals, oil & Gas and general industry (cement, water treatment, rubber and plastic, materials handling, glass, ceramics, paper and ropeway). Since 2014, Giovanni Barra has been CEO of Nidec ASI Nidec Leroy-Somer. On January 31, 2017, Nidec acquired Leroy-Somer from Emerson Electric which became Nidec Leroy-Somer Holding. Nidec Global Appliance Compressors GmbH. On July 31, 2017, Nidec acquired Secop GmbH, a German hermetic compressor manufacturer from Aurelius Equity Group, expanding further into the refrigeration market. Since April 28, 2018, Nidec has entered into an agreement with Whirlpool Corporation to acquire the refrigeration compressor business of Embraco. In response to antitrust concerns, in 2019 Nidec sold Secop. In November 2018, Nidec became a shareholder of Nidec Chaun-Choung Technology Corporation, a long-established cooling company in Taiwan. In December 2019, it again announced that it would increase its shareholding from 49.01% to 53.48%, and reached 67% shareholding in December 2020.

Worked examples

Example 1 — a first encounter with Nidec

Start with the simplest possible case. Write down what Nidec claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nidec before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nidec ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nidec

In research: Nidec appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nidec in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nidec is common in secondary-school and first-year university syllabi. It links to neighbouring topics Auto parts suppliers of Japan, Companies listed on the New York Stock Exchange, Companies listed on the Osaka Exchange, so understanding it makes those chapters shorter.
In everyday life: Look for Nidec outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Nidec in simple terms?

Why does Nidec matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Nidec?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
