TOKYO (Reuters) - Japan's Nidec Corp said on Wednesday it had filed a patent infringement lawsuit against Seagate Technology LLC and its affiliates, accusing it of using Nidec hard disk drive motor designs without permission.

The suit was filed on Jan. 18 in the U.S. District Court in Delaware, Nidec said in a statement.

The Japanese component maker wants the court to award it appropriate compensation based on sales made by Seagate, a Nidec spokesman said.

At issue were spindle motor designs used to spin the HDD disk and the base plate the disk sits in, the spokesman said.

Seagate did not immediately respond to a request for comment.

Nidec has about 85% of the global market for HDD motors, which are used in computers and other devices including data centre equipment. Those motors account for around a tenth of the company's revenue.
