Product Information

S-33 Motor and Control (OEM Application)

These BLDC Motors and their Control give significantly improved performance due to the number of poles and high frequency operation. The motor is designed on 8 pole configuration and the control is built on the rear side of the motor. Necessary heat sink are fabricated / mounted on the unit for handling heat transfer.

There are 2 basic models of these motors – one has a power output of 375W & is rated at 0.8 N-m while the other has a power output of 750W & is rated at 1.5 N-m. A local host based on Microcontroller can be used to manually control Speed & Direction of the motor. These motors are available with integral gearbox combinations also.

Features:

Continuous operation
High efficiency (>80% for Motor + Control)
Low EMI / EMC
Low Inertia
Multi-drive networking
Local Host Control
Isolated Interface
2 modes of operation

o Velocity mode

§ Direction, Speed & Acceleration curve (plotted against time scale) can be programmed

§ Motor works according to programmed profile

o Position mode

§ Speed & Acceleration curve (plotted against time scale) can be programmed

§ Absolute or relative position(s) can be programmed

§ Motor works according to desired position(s)

Applications:

Industrial Automation
Process plants
Winding machine
Garment factory
General purpose control

SMPS / Battery Charger (OEM Application)

Vibration Controller

The Vibration Controller is based on Analog Devices BlackFin 533 DSP which is one of the most powerful DSP available. It also includes 24 bit ADC and DAC to provide excellent dynamic range with low noise. The signal processing is implemented at 32 bit resolution therefore the system offers noise level below 100 db.

This system is available with sine, random and shock software and it uses visual basic based open GUI.
