2019年10月17日 · In this session, I’ll explain how we can control an independent HDD BLDC motor effectively. To rotate a BLDC motor, we need to control the direction and timing of the current into the stator coils, but that drive method is more complicated.

Thin PC design requires the use of thinner components, and Nidec, the global market leader in the HDD spindle motor market, supports the evolution of notebook PCs by providing thinner motors. Currently, 7 mm thick HDDs are in mainstream use for notebook PCs.

2024年10月30日 · HDD Solid Shaft is our most sold servo motor. Available in a torque range from 1.2 Nm to 10 Nm, rated 3000 or 6000 rpm and wound for 230 or 400 VAC. The motor is equipped with keyway, straight connectors, resolver feedback, PTC thermal sensor and IP-65 protected and can be supplied with a brake.

2013年4月19日 · You can't easily control the HDD motor via IDE cable. Unlike floppy drives, where motor commands are directly send over the IDE cable, on hard disk drives, the drive's controller is expected to calculate cluster position and actuate the motor.

Ball Bearing spindle motors have been the common design-in for HDDs for many years; however, the market is shifting toward a diferent type of bearing design known as Fluid Dynamic Bearings (FDB). This white paper addresses why this change is taking place and the attributes and issues associated with these designs.

Hard Disk Drive (HDD) spindle motors are what cause the disks in HDDs to rotate. The precision of these motors determine the capacity and speed of HDDs, making these components critical to HDD performance.

近几年的超薄型笔记本电脑。 核心设备HDD用马达。 PC薄型化也就是其内置设备的薄型化，在HDD主轴马达拥有全球No.1市场占有率的NIDEC（尼得科）也通过马达的薄型化来支持笔记本电脑的升级发展。 当前，笔记本电脑中使用的HDD主流产品的厚度为7mm。

The HDD Solid Shaft Motor is our most sold motor. The motors are available in 90 – and 140 mm frame sizes, in a torque range from 1.2 Nm to 10 Nm, rated 3000 or 6000 rpm and wound for 230 or 400 VAC.

The unique HDD technology with an integrated bellow coupling, enables a more compact installation of servo motors. The motors are available in 92 – and 140 mm frame sizes, in a torque range from 2.3 Nm to 10 Nm, rated 3000 rpm and wound for 230 or 400 VAC.

2018年5月8日 · A typical HDD has two electric motors; a spindle motor that spins the disks and an actuator (motor) that positions the read/write head assembly across the spinning disks. The disk motor has an external rotor attached to the disks; the stator windings are fixed in place.
