33 Adjustable Speed Drive (ASD) Control P2/E2 Site Assessment Grant Program Training
34 ASD - Background Provides the ability to precisely match motor output to process requirements. Power varies as the cube of speed Most effective for applications with varying loads. Common applications: fans, compressors, pumps P2/E2 Site Assessment Grant Program Training
35 ASD - Potential Benefits Improved product quality Improved process throughput Improved process control Energy savings Reduced maintenance
36 Common Problems with VFDs VFDs create dirty power (odd-power harmonics) which can upset sensitive equipment Early bearing failure Doesn t save energy when motor is at full load Low speeds can cause cogging
37 Flow Control Methods Use of outlet dampers and throttle valves Change head pressure to control flow rate Control motor speed
38 Flow Control without ASD Motor runs at constant speed Flow rate controlled by valve
39 Power Source Flow Control without ASD Signal Control Valve Controlled Flow Pump Motor
40 Flow Control with ASD Motor speed varies Flow rate controlled by motor speed Energy is saved
41 Power Source ASD Flow Control with ASD Signal Controlled Flow Pump Motor
42 Types of ASDs Mechanical Hydraulic clutches Adjustable belts and pulleys Electrical (Variable Frequency Drives) Pulse Width Modulated (PWM) Voltage Source Inverter (VSI) Current Source Inverter (CSI) Brushless DC Drive (BDCD) Switched Reluctance Drive (SR) Flux Vector Drive (FV)
43 Pulse Width Modulated (PWM) Uses complex computer software Motor frequency produced with sinusoidally varying pulses of voltage Advantages High power factor Can control several motors at once Smooth speed control, even at low speeds, which eliminates cogging Responds very quickly to speed changes Suitable for almost all applications
44 PWM Disadvantages Over voltage may lead to failure for motors under 50 hp Decrease cable length between motor and ASD Noisy operation Early bearing failure Use shaft grinding brush instead of graphite grease
45 Voltage Source Inverter (VSI) Use simple electronic circuit Advantages Able to control several motors at once Very high speed drives available Disadvantages Speed control close to zero unavailable Low frequency results in cogging Power factor proportional to speed No regenerative braking
46 Current Source Inverter (CSI) Mostly replaced with PWM Advantages Capable of regenerative braking Disadvantages Difficulty controlling more than one motor Poor performance below 50% of rated load
47 Brushless DC Drive (BDCD) Uses permanent magnets on rotor as poles Advantages Motor shaft speed and position controlled very accurately Able to quickly reaccelerate to high speeds Disadvantages Limited to motors with permanent magnets
48 Switched Reluctance Drive (SR) Configured specifically for switched reluctance motors Advantages Wide speed range Dynamic response Disadvantages Expensive Cogging occurs close to zero speed
49 Flux Vector Drive (FV) Best available control Uses same basic control as PWM Advantages Allows maximum torque performance Calculates exact direction and magnitude of motor flux Disadvantages Very expensive should only be used if superior control is needed
50 ASD Efficiency Efficiency with which ASDs convert constant-frequency power into adjustablefrequency power decreases with speed Uses 4-6% more of the full-load nameplate horsepower while running at full-load Cogging may occur
