The INVERTEK EasyServo family of servo amplifiers is an economical solution to today’s complex motioncontrol needs. The EasyServo combines a Digital Signal Processor (DSP), controller, heat sink and power supply in one standalone, DIN-rail mountable or panel-mounted unit. The EasyServo can be operated as a stand-alone unit or as a digital amplifier.

The EasyServo controls brushless motors with a high switching (carrier) frequency for virtually silent operation. Most servomotors used today require high precision control and a smooth, sinusoidally commutated signal. An on-board DSP provides commutation by generating the three-phase sine wave, using feedback information from an optical encoder.

The servo will accept feedback from an encoder that includes Hall sensor feedback information. It accepts commands from a variety of sources, including analog voltage, PWM and internal reference signals. The control will operate in current (torque) mode, velocity mode, or position (step and direction) mode. Upon initial start up, the motor is commutated using the hall sensors—for the first two or three mechanical degrees of motor rotation—to map the encoder; The hall-effect information is unnecessary thereafter.

The EasyServo’s built-in RS-232 serial communications port and servo control program,
MotionView™, make programming extremely simple. In fact, you could be up and running in less than thirty minutes! Each EasyServo unit is an amplifier, power supply, controller and heat sink integrated into a single standalone package. The EasyServo will only accept an encoder with Hall or an encoder with hall-commutation tracks encoded on the feedback device.

The ESM series brushless servomotor with permanent magnet is designed and manufactured for most of industrial applications, which require high performance, fast dynamic response, good reliability, and fre maintenance.

The ESM servomotor is made use of new advanced material such as Neodymium iron, Boron Magnet, low loss Silicon Steel Sheet, to ensure excellent performances as including of:

• High power density with low overall dimensions
• High overload capability
• Low moment of rotor inertia, perform very high dynamic response
• Low weight
• Sinusoidal B.E.M.F.
• Low cogging torque
• High accuracy
