Type AWM-B310 Advanced Automatic Double Flier Armature Winder
Type AWM-ECO-MINI Economic Automatic Double Flier Armature Winder

We offer two models one of which is a fully featured AWM-B310 – Advanced Automatic Double Flier Armature Winder and the other the AWM-ECO-MINI– Economic Automatic Double Flier Armature Winder. While the B310 type is targeting the applications in automotive and advanced Power tool motor winding applications, the ECO-MINI addresses the winding needs of appliances motors at lower investments. Both machines are automatic armature winders capable of winding two pole hook type commutators

Diamond Turning Machine

The DTM-2X Diamond Turning Machine has been designed for turning operations on Commutators. The DTM-2X is of modular design and essentially comprises of a solid heavy machine base housing a servo linear slide and a servo cross slide and a tool holder. The Armature while being turned is supported free across two Diamond V Block supports on the bearing area to facilitate stress free center-less turning. a

A separate swivel frame, which is mounted on the rear of the base frame, houses a belt drive assembly meant for rotation of the armature through friction on the OD of the Armature stack. An induction motor with a V/F drive to run the belt facilitates on the fly surface speed variation. The belt drive assembly uses a spring tensioner to compensate tension and ensure that the Armature does not lift or slip during the turning operation. This frame being isolated for vibration from the main bed reduces vibrations being transferred to the armature while turning.

The Longitudinal traverse of the tool post is controlled by a precision electrical AC Servomotor coupled to a ball-screw driven slide. The cross slide is also servomotor driven and as such both diameter and the travel are programmable

The Rotor Turning Machine
The RTM03 type Rotor Turning Machine has been designed for turning Stack of rotors of AC induction motors. The RTM03 comprises of a solid heavy machine base housing a linear slide and a cross slide with a tool holder. The Rotor while being turned is supported free across two Rotor Roller Block supports on the bearing area to facilitate stress free center-less turning. A separate swivel frame, which is mounted on the rear of the base frame, houses a belt drive assembly meant for rotation of the rotor through friction on the OD of the Rotor stack. An induction motor with a V/F drive to run the belt facilitates on the fly surface speed variation. The belt drive assembly uses a spring tensioner to compensate tension and ensure that the Rotor does not lift or slip during the turning operation. This frame being isolated for vibration from the main bed reduces vibrations being transferred to the rotor while turning. The machine is controlled by a DSP based controller that is interfaced with the prime movers of longitudinal traverse and the cross feed of the tool post as well as the inputs and outputs used for machine functions. The traverse and functions are controlled by either AC Servo Motors or Hydraulics as detailed below for the customer to choose the required option.

PC Based Armature Tester

The Armature tester is designed to conduct joint resistance test , bar to bar resistance test, hi-voltage test and surge test of an armature. The Microprocessor based Armature Tester includes Electronic Modules for testing, rotary testing fixture driven by stepper motor with holding assembly for armature. The tester equipment is a PC controlled test rig, to conduct the required tests and to acquire its data, to process it and give out results.

Bar to bar resistance with thermal compensation: 1.00 - 200.00mW with measurement resolution of 0.025 mW and display resolution of 0.001 mW

Joint resistance with thermal compensation: 0.00 - 0.25 mW with measurement resolution of 0.025 mW and display resolution of 0.001 mW

Hi - Voltage test: Permissible leakage 20mA

Surge Test : 500 or 1000 V DC

The equipment will be suitable for operation on 230 V +/- 2% AC, 50 Hz. It acquires data through precision probes on the commutator connected to electronics and functions through an integrated logic control. Provisions for easy load and unload of components is provided. Indexing of the armature is through a belt driven assembly connected to a stepper motor.

All measurement electronics will be on modular dedicated micro controller based units with communication channels to integrate with the user interface provided in the PC

Software features will be provided in the user interface for easy operation that will include but not limited to storage of data, compilation of results, on line printing, selection of job profiles, display of related data etc.
