Product Overview

It is a premium, fully-featured motion control platform, designed for demanding applications that require superior performance and integration flexibility.

The NSP-BLDC4820B brushless DC (BLDC) motor drive is the latest high-tech product launched by our company, targeting the medium-power brushless motor drive field. This product adopts large-scale integrated circuits (LSIC) to replace the original hardware design, featuring higher anti-interference capability and fast response performance. It is suitable for driving any three-phase low-voltage BLDC motor (with or without Hall sensors) with a peak current of less than 25A and a power supply voltage ranging from DC 18V to 60V, and boasts the characteristic of low temperature during high-current operation. The product is applied in a series of electrical automation control fields such as knitting equipment, medical equipment, food packaging machinery, and power tools.

Key Features

  • Can be connected to a computer to configure the drive’s parameters.
  • Dual closed-loop design for current and speed, featuring high torque at low speeds and smooth operation.
  • High torque and high speed output, with a maximum speed of up to 10000rpm/min.
  • Speed control method: 0–5V analog speed regulation.
  • Equipped with signal input terminals including EN (Start/Stop), DIR (Direction), and Brake (Electromagnetic Brake).
  • Can output speed signal, fault signal, etc.
  • Protections include overcurrent, overvoltage, undervoltage, and motor stall.
