| AC24 Motor, AT1200 Gearbox and
DMOC445 Digital Controller Overview The Azure Dynamics AC24 with DMOC445 Drive System features the Azure AC24 motor with an optional AT1200 gearbox with internal differential. This drive system is designed with front wheel compact sedans in mind. Vehicle conversions are made fast and easy, because this motor/gearbox assembly will easily replace the engine and transmission of many compact front wheel drive vehicles. If direct drive or connection to an existing gearbox or transmission is desired, the AC24 is available without the AT1200 gearbox and with a NEMA C-face. Applications & Features In battery EV applications, the AC24 with DMOC445 drives are designed for use in vehicles weighing from 1,000 to 3,500 lbs. The optional gearbox provides a 10:1 overall vehicle drive ratio with differential included. Mating half shafts are also available. AC24 Motor • High-efficiency air-cooled AC induction motor • Sealed motor and gearbox casings • Compact, lightweight construction • Low rotating losses and motor electrical resistance Optional AT1200 Gearbox • Precision ground helical gears for quiet operation and long system life DMOC445 Digital Motor Controller Azure’s DMOC445 is a DSP-controlled, rugged, waterproof (except for cooling fans) inverter for controlling 3-phase AC motors and generators. Liquid-cooling is available. • DSP-based control • Regenerative braking • Space Vector PWM and Field Oriented Control • Internal contactor with pre charge circuitry • Speedometer driver for some dashboard displays/gauges (such as VDO) and brake light enable • Lightweight aluminum chassis • Waterproof, rugged construction • Trenchgate IGBTs for maximum efficiency • Over voltage and under voltage protection • Three-level over current protection >10kHz DSP-based current control >Analog over current watchdog >”Desat” protection at gate level • Inverter over temperature protection • Motor over temperature protection • Over speed torque limit • Invalid pedal signal detection • RS232 – for diagnostics and data visualization • CAN – for communications with other components EFFICIENCY CHART 300V VERSION POWER CHART 150V VERSION POWER CHART AC24 3-VIEW DIMENSIONS AT1200 3-VIEW GEARBOX DIMENSIONS |

| Azure AC55 Motor and DMOC445 Digital Controller Overview The Azure Dynamics AC55 with DMOC445 Drive System features the Azure AC55 motor mounted in an axial design. This single motor directly drives the differential, typically via a short drive shaft. Because of the direct drive layout, the drive unit fits into the area formerly occupied by the traditional drive shaft of delivery vans, trucks, etc., making vehicle conversions fast and easy. Applications & Features In battery-EV applications, the AC55 and DMOC445 drives are designed for use in vans, trucks and buses weighing from 5,000 to 11,000 lbs. The motor is of a low-speed design for a typical 3-5:1 overall vehicle drive ratio. • AC induction motor • Air-cooled • High-efficiency brushless design • Compact, lightweight construction • Low rotating losses • Low electrical resistance • Cost effectiveness and high reliability • Because it is used in conjunction with an Azure DMOC motor controller, the AC55 can function as an “electronic transmission,” eliminating the need for a multi-speed gearbox in some applications, directly driving the vehicle’s wheels with a fixed ratio. DMOC445 Digital Motor Controller Azure’s DMOC445 is a DSP-controlled, rugged, waterproof (except for cooling fans) inverter for controlling 3-phase AC motors and generators. Liquid-cooling is available. • DSP-based control • Regenerative braking • Space Vector PWM and Field Oriented Control • Internal contactor with precharge circuitry • Speedometer driver for some dashboard displays/gauges (such as VDO) and brake light enable • Lightweight aluminum chassis • Waterproof, rugged construction • Trenchgate IGBTs for maximum efficiency • Over voltage and under voltage protection • Three-level over current protection >10kHz DSP-based current control >Analog over current watchdog >”Desat” protection at gate level • Inverter over temperature protection • Motor over temperature protection • Over speed torque limit • Invalid pedal signal detection • RS232 – for diagnostics and data visualization • CAN – for communications with other components TORQUE-SPEED AND POWER-SPEED CHART TORQUE-EFFICIENCY CHART LOW SPEED TORQUE CHART AC55 3-VIEW DIMENSIONS |
