Advantages of compact drives The basis of VEM compact drive are two components, the robust VEM grey cast iron motor and a drive electronic that is optimised for motor operation. When thinking about the engineering design, the most importance was attached to a high vibration strength of the inverter and a sound design of the whole drive unit. Whereas the inverters of the design series M21...T will be cooled by the ventilator of the motor, the inverters of the design series M21... possess a separate ventilation system. The compact drives are available in all standard types of construction,...

Compact drives of series M21 ... T 0.55 to 7.5 kW (vector controlled design) For this design variation the cooling of the inverter is integrated in the cooling system of the motor, that means the cooling will be done by the ventilator of the motor or if necessary by an axially mounted forced-ventilation unit of the motor. Due to favourable motor connection of the inverter and the small dimensions, the mounting space of the standard asynchronous motor will be exceeded only slightly. The special product advantages of this design variation are: • type of protection IP 55, IP 66 as option •...

Compact drives of series M21 ... VS 5.5 to 22 kW (vector controlled design version) The inverter is fitted with a ventilation system that is independent of the motor. The speed of the drive can be adjusted without external control panel in the standard design version (M version). Comfortable means of operation are: • external unit for operation and change of parameters • serial interface RS 485 • Bus connections • customer modified interface Remarkable is the variety of serial interfaces: • 8 digital inputs with free choice of parameters and potential separation • 2 analogue inputs with...
