Brushless motor RESMAX 28 EE

3-phase24 Vpermanent magnet

High Speed ResMax 28 EE Brushless DC Motors The ResMax 28 EE is a 3-phase brushless DC motor with a two-pole NdFeB magnet rotor. The motor is designed to operate at high speeds of up to 90,000 RPM. Its very low inertia rotor design gives the ResMax 28 motor a time constant of just 4 milliseconds, which makes it ideal for highly dynamic applications like respirators and CPAP equipment. Acceleration capability, even with an extra load, is 0 to 50,000 RPM in only 100 milliseconds. The ResMax 28 is designed to have low thermal losses at high speeds, which together with its low thermal resistance rating of 1.2 °C/W from winding to housing keeps the motor cool. Lower motor temperature also benefits bearing life; bearing life is 30,000+ hours at high dynamic operating conditions. These features make the ResMax 28 motor ideally suited for high speed, highly dynamic applications. Features & Benefits - Up to 90% efficiency - Optimized for high speed operation - Three Hall sensors for external three phase motor control - Integrated NTC sensor to monitor motor winding temperature - Compact motor with length of just 40 mm
