All featured motors are liquid cooled AC induction (BRUSA HSM6.17.12 is hybrid) machines designed specifically for use in electric vehicles and to work with matching power inverters. The rated (1 hr) power ranges from 3.5 kW to 67 kW. All models will handle higher (2x...3x) peak power, often limited only by the inverter. Siemens motors have built in shaft speed and position sensor, interfaced to the power inverter. The shaft RPM signal is available from the inverter's interface to the dash panel in the form of either variable frequency square wave to drive stock tachometer, or binary encoded if digital RPM display is preferred. Motors may come with different shaft and front flange options. MES motors with <24 kW can be ordered with or without fixed single gear reduction box. Optionally motors have mechanical or electronic output for speedometer and integrated parking brake. BRUSA HSM6.17.12 hybrid motor is special type; its design and characteristics are blend of induction and synchronous motors - they feature squirrel cage rotor as for ASM6.17.12 motor with embedded rare earth permanent magners making motor behaving aat high RPM more like synchromous machines than induction ones. Distinctive advantage is nearly constant power curve at constant power region up to the top RPM unlike distinctive fall off for induction motor. The MES 200-75 through MES200-150 motors can be supplied with or without Carraro gearbox which contains single 8.654:1 reduction gear and differential ready to be linked with half-shafts of a vehicle. The rated power Carraro gear box can handle is 30kW, therefore higher power motors (200-175 and above) cannot be used with this gear box. |
