Product Description:

The Inland Direct Drive Motor TM Kollmorgen TT-2939-A is a compact and powerful motor for precise control and high performance. It consumes about 10 watts of power, and it operates on a DC input voltage range of 12 to 24 Volts. This IP67-rated motor can supply an output current up to 3 amps. Its 100 x 50 x 30 millimeter dimensions mean it can be used where space is limited. The motor is flange mounted with a stator and flange mounted, through-hole, and it features a frameless, hollow shaft style rotor. Natural convection cooling is standard, but it also offers the option for forced air or liquid cooling to help control heat in diverse working environments.

An important feature of this motor is its insulation class F (155 degrees C). This rating indicates how safely the motor can handle heat during operation. In a motor, Insulation prevents the internal parts of the motor from any kind of damage. A Class F insulation means that the motor's internal wiring and materials can safely operate at 155 degrees Celsius without breaking down. This means that the motor works more reliably in tough conditions and doesn't heat up or fail easily.

In addition, the motor delivers a strong peak torque of about 60 to 100 Newton-meters, depending upon the winding and cooling method. Torque is the rotating force the motor can generate for short time periods, during start-ups or heavy load conditions. The amount of torque the motor can safely offer plays an important role in the cooling system. Forced air or liquid cooling helps the motor manage more power without overheating. The TT-2939-A motor is a versatile and powerful option for many single-phase, industrial and automation applications.
