TGT servomotors

Brief description

tgt.jpg The TGT series AC synchronous servomotors are characterized by low inertia, small dimensions, high dynamics, high adaptability and great reliability. The TGT servomotor series are featured for wide purpose applications. The winding is designed for sinusoidal current and voltage. The thin NIB magnets (neodymium / iron / boron) embedded on circumference of the rotor shaft resulting the small inertia of the motor. The skewed stator laminations and skewed alignment of the rotor magnets decrease the torque pulsations and cogging.

Ranges

The TGT motors are available in 8 sizes: TGT1-TGT 8 with the torque range from 0,1 Nm to 115 Nm.
The TGT servomotors are produced for different DC-bus voltages (24V, 36V, 48V, 320V, 560V) and for different nominal speed (500, 1000, 1500, 2000, 3000, 4500 rpm). The catalogue includes motors with nominal speed 3000 rpm (except TGT1, TGT2 and TGT3 – 6000 rpm) and DC-bus voltage 24V or 36V, 320V and 560V. We can send you technical parameters of motors designed for other DC-bus or speed on demand
Likewise both TGT motors and TGH servomotors can be fitted with different feedback types. The standard sensor for common applications is the resolver. For very precise applications the encoders with EnDat or Hiperface interface are the most appropriate. The Comcoder could be mounted as well.

Technical features

Holding Brake

The motor can be delivered with or without a built-in electromagnetic holding brake. The brake is not intended for the positioning. The purpose of the brake is to lock the motor in zero speed.
Supply voltage: 24VDC –0% + 10%
Location: at shaft motor part

Feedback units

The flexible design of servomotors allows different feedback sensor mounting. The most frequent types are:

Resolver is a brushless electric appli-ance, used for rotor position measuring and for commutation angle derivation. Resolver is commonly used as a position and angle speed sensor in regulation circuits of servoamplifiers.

EnDat is high resolution encoder with a data channel. The absolute position is sent through a fast serial interface. The sinus – cosine shape of the incremental signals (1Vpp) provides highly accurate positioning. (100.000 increments per revolution). The EnDat sensor could be single-turn or multi-turn (4096 turns).

Hiperface is – like EnDat – a high resolution encoder with a data channel. The absolute position is sent through a fast serial interface. The sinus – cosine shape of the incremental signals (1Vpp) provides highly accurate positioning. (100.000 increments per revolution). The sensor could be single-turn or multi-turn (4096 turns).

Comcoder I is a combined incremental encoder. An absolute position is given through the commutation signalsof three Halls. The incremental signals(5V TTL) provides accurate positioning.

Temperature protection

The temperature of the winding is monitored by sensors in the stator windings. The temperature is then signaled via an electrically isolated contact (thermo contact or posistor). The sensors are set so that the winding temperature does not exceed 130°C. The type of temperature protection should be specified.
