A.C. Synchronous Servo Motor

These motors are operated from single phase source with R-C Phase shifting network. The speed of the motor is proportional to applied frequency of the supply. It attains its full synchronous speed within 5 to 25 ms. We manufacture various models of motors with torque capacities of 2.5, 3, 5, 7,10, 20, 30, 40, 60 kg.cm. We also make as per your requirements.

Our range is manufactured by using high grade copper, stampings, milmex paper, varnish, inner, rods and shafts

Features:

Permanent Magnet AC Motors - No winding on rotor.
Extremely rapid starting, stopping and reversing characteristics.
Basic constant synchronous speed of 60 rpm at 50 Hz.
Torque from 2 kg.cm to 60 kg.cm.
Gearing possible to achieve reduced speeds Built in overload protection -motor stops if overloaded but does not burn.
Starting and operating currents are identical.
Magnetically rotor can be locked by D.C. applying.
Power coated cast aluminium body with steel shaft.

Applications: 
These motors are finding applications in servo control applications where precise positioning is required. The Instantaneous starting stopping and reversing characteristics of the motors make them very aptly suited for following applications among many:

Servo Voltage Stabilizers.
Diamond machines.
D.C Drives.
Precise positioning.
Valve Controls.
Automated Welding Equipments.
Medical Equipments.
Conveyor Systems.
Actuators.
Fluid Metering.
Textile edge guide control.
Paper Feed.

Characteristics:

A.C. Operation : Motor can be directly connected to 240 V; 50Hz, supply along with "APPLE" supplied R-C network in series with one of the stator winding. Change of this R-C network from one winding to other results reversal of motor direction. Single pole three position switch can be used for Forward, Reverse and Off control as shown in the following diagram. Metal varistor oxide may be used to minimize the switch contact arcing.
Starting : Motor start within 1 1/2 Cycles of its applied frequency & will reach 60 RPM within 5 to 30 ms at 50 Hz. Since motor has no significant current rise on starting, this motor is ideal to an application which requires six or more starts per minute.
Stalling : Motor will not be overheated if stalled because starting, full load and no load currents are same. However prolonged operation against a solid stop will eventually produce bearing failure due to the resultant shaft vibrations.
Inertia Limitations : Since the motors are having extremely rapid starting, there is a limit to the inertia load at which the motor will start from rest. Addition of resilient coupling with app. 5 degree of rotational freedom or gearing with backlash between motor & load can increase the permissible inertia load handing capability.
Phase Shift Network : The values of R-C network have considerable effect on motor performance. They have been chosen by "APPLE"' in such a manner that no reverse torque is produced when voltage is applied. 
R-C values should not be varied more than 5% so as to enhance smoother starting, give quieter operation, maximize torque & improve efficiency.

Other values may be recommended by "APPLE" for the continuous duty specific OEM application.
Stopping & Holding (Braking) : Due to magnetic rotor, these motors decelerate faster than conventional motors and stop within 5 degree after turnoff with no external inertia. Application of D.C. supply to one or both motor windings after removal of A.C. supply results deceleration time 1/10th to 1/20th those available with conventional motor & the motor shaft is electrically locked after the stop. A typical circuit for applying, stopping & or holding current is shown in the following diagram.
Back Driving : These motors act as generators when back driven. Rotating in access of 1400 RPM is not recommended because high voltages can be generated. At 1400 RPM or below suitable precautions for protection of personnel/phase shift capacitor & any other connected circuitry may be necessary when back driving.
60 Hz Operation : These motors may be operated on 60 Hz, but may require a different R-C network, the factory must be consulted. Torque rating should be similar to those shown for 50Hz & speed is 72 RPM @ 60 Hz.

Our OSA 5410 Series is a family of compact and costeffective synchronization distribution and assurance devices that brings the power of Syncjack™ to any access network. The OSA 5410 Series offers unique flexibility by supporting delivery and assurance of synchronization utilizing Synchronous Ethernet and IEEE 1588v2 Precision Time Protocol (PTP). Thanks to its builtin Global Navigation Satellite System (GNSS) receiver and Grandmaster (GM) Clock capability, it can be used as a timing source for frequency, phase and time-ofday delivery, as well as a measurement reference for Syncjack™ tools. Our OSA 5410 Series supports Assisted Partial Timing Support (APTS) for the most stringent timing applications. An internal high-quality oven-controlled crystal oscillator (OCXO) or a rubidium oscillator option enable extended holdover capabilities. Applications The family members of our OSA 5410 Series can be utilized in a variety of network synchronization applications, including IEEE 1588v2 Access Grandmaster, Boundary and Slave Clock, APTS Clock, GNSS receiver and Primary Reference Time Clock (PRTC), synchronization signal conversion and sync probe applications. Our OSA 5410 Series is designed to deliver the accurate phase and frequency required by next-generation network technologies such as LTE-A, LTE-TDD and enterprise networks. Timing can be easily distributed and assured throughout a network over existing packet infrastructure. Timing performance is continuously monitored while in service, and alarms are triggered if needed. A valuable new approach for timing distribution is made available to mobile network operators: the ability to effi ciently distribute timing from the network edge and assure that base station clocks precisely track their master. Syncjack™ Monitoring and Assurance Tools Our OSA 5410 Series supports all Syncjack™ functions and tools. Syncjack™ is a comprehensive technology for timing distribution, monitoring and timing service assurance. Syncjack™ Clock Accuracy measures the frequency and phase accuracy of physical clock signals relative to a synchronization reference. Syncjack™ continuously performs Clock Analysis, including frequency and phase accuracy of the PTP packet domain. Syncjack™ also performs PTP network analysis, as well as monitoring and testing the PTP communication path. Our OSA 5410 Series uses Syncjack™ tools to measure frequency and phase accuracy of a physical clock source or a remote slave clock based on TE, TIE and MTIE. It performs PTP clock analysis by calculating TE, TIE and MTIE from timestamps embedded in PTP messages. The network probe function complements the clock measurement through network analysis of the PTP message transport. All functions are supported by our FSP Sync Manager, an advanced management platform for timing distribution and assurance.
